These comments come from the White Christmas thread but bear repeating herein as they relate to your post about the newly minted Sepia Records CD release of the 'soundtracks' to both White Christmas and Holiday Inn.
I'm going to cover the track listings here; which are original and which are alternate, or, not from the movies themselves. My comments are in brackets after each track listing. Please note, my use of the word 'original' denotes the authenticity of the track as the movie version while NOT directly derived from the film soundtrack, but otherwise taken from magnetic stereo pre-recordings that have survived.
*Please also keep in mind, Martha Mears dubbed for Marjorie Reynolds in Holiday Inn, and Trudy Stevens did the same for Vera Ellen in White Christmas. These ARE the original artists heard in the movie soundtracks.
CD 1
WHITE CHRISTMAS
1. VISTAVISION FANFARE The Paramount Studio Orchestra (original)
2. WHITE CHRISTMAS MAIN TITLE The Paramount Studio Orchestra (original)
3. SANTA CLAUS Bing Crosby, Danny Kaye (a Berlin tune planned for the movie but never actually heard in it. This song was to entertain the troops in the field on the eve of their invasion. In the movie version, Crosby and Kaye merely do a buck and wing to an orchestral 'tag' of this song that, ironically, is NOT a part of this song version heard on the CD).
4. WHITE CHRISTMAS Bing Crosby (original, minus the distant SFX of exploding wartime shells)
5. WE'LL FOLLOW THE OLD MAN Bing Crosby, Danny Kaye (original, again without any SFX)
6. HEAT WAVE, LET ME SING AND I'M HAPPY, BLUE SKIES Bing Crosby, Danny Kaye (derived from the movie soundtrack, not an original mag tape master. So, background SFX remain)
7. SISTERS Rosemary Clooney, Trudy Stevens (curiously, missing the 'montage' orchestral track that precedes it and takes us to the Floridian nightclub, Novello's, but otherwise, intact, and with an extra verse and chorus NEVER heard in the movie)
8. THE BEST THINGS HAPPEN WHILE YOU'RE DANCING Danny Kaye (unfortunately taken from the movie soundtrack, with SFX and distorted tap sounds)
9. SNOW Bing Crosby, Danny Kaye, Rosemary Clooney, Trudy Stevens (original, but with added verse and chorus, and an alternate ending to the version heard in the finished film)
10. SISTERS (Reprise) Rosemary Clooney, Trudy Stevens (this is not the Crosby/Kaye lip sync version as they foil the sheriff's incarceration of Clooney and Vera Ellen's characters, but rather the truncated 'inn' version the girl's debut on their first night as the general's floor show. Derived from the movie soundtrack with SFX heard in background)
11. I'D RATHER SEE A MINSTREL SHOW, MANDY Bing Crosby, Danny Kaye, Rosemary Clooney (original, minus SFX)
12. COUNT YOUR BLESSINGS INSTEAD OF SHEEP Bing Crosby, Rosemary Clooney (original, minus SFX)
13. CHOREOGRAPHY Danny Kaye (original and the first time we get to hear Kaye's song without the horrendous distortion of its movie version incarnation. There are moments in the movie cut that truly grate on the ears. This version is in stereo and sounds magnificent)
14. THE BEST THINGS HAPPEN WHILE YOU'RE DANCING (reprise) The Skylarks (original, without SFK or background dialogue)
15. ABRAHAM Instrumental (unfortunately, the movie version, with background hiss, dialogue and distortion built-in)
16. LOVE, YOU DIDN'T DO RIGHT BY ME Rosemary Clooney (original, no SFX)
17. WHAT CAN YOU DO WITH A GENERAL Bing Crosby (original, but with an added verse and chorus NEVER heard in the movie cut)
18. WE'LL FOLLOW THE OLD MAN (Reprise) Bing Crosby, Danny Kaye (original)
19. GEE, I WISH I WAS BACK IN THE ARMY Bing Crosby, Danny Kaye, Rosemary Clooney, Trudy Stevens (original)
20. WHITE CHRISTMAS FINALE (version 1) The Paramount Studio Orchestra (this is the first half of the version heard in the movie. It ends with a truncated reprise of the song by the children's chorus, minus the orchestral tag that followed as Crosby and Kaye discuss their plans to wed the Haines' sisters and settle down. This version does not conclude with the orchestral accompaniment that continues in the film as the bay doors of the inn's stage are parted to reveal the gentle snow falling just beyond and the reprise of the song. This is an incomplete track)
21. WHITE CHRISTMAS FINALE (version 2) Bing Crosby, Danny Kaye, Rosemary Clooney, Trudy Stevens (an alternate version of the finale with less choral fanfare than the version heard in the movie)
22. WHITE CHRISTMAS FINALE (version 3) Bing Crosby, Danny Kaye, Rosemary Clooney, Trudy Stevens (strictly a track featuring the four principal players and a subtle ending NOT heard in the movie)
23. WHITE CHRISTMAS FINALE (version 4) Bing Crosby, Danny Kaye, Rosemary Clooney, Trudy Stevens (this is a truncated version of the tag that concludes the movie version of the song, minus the applause track and the tag that ought to have accompanied the aforementioned parting of the inn bay doors to reveal the snow falling outside. Instead, this track picks up with the reprise of the song and the finale as is heard in the movie's final edit)
(Tracks 24 through 29 are from Rosemary Clooney's re-release of a 'soundtrack' album from 1954 and have NO bearing on the movie cuts.)
24. WHITE CHRISTMAS Rosemary Clooney
25. SISTERS Rosemary, Betty Clooney
26. SNOW Rosemary Clooney
27. COUNT YOUR BLESSINGS INSTEAD OF SHEEP Rosemary Clooney
28. LOVE, YOU DIDN'T DO RIGHT BY ME Rosemary Clooney
29. IRVING BERLIN'S WHITE CHRISTMAS THEATRE LOBBY ANNOUNCEMENT Bing Crosby
CD 2
HOLIDAY INN
1. HOLIDAY INN MAIN TITLE The Paramount Studio Orchestra (original)
2. I'LL CAPTURE YOUR HEART Bing Crosby, Fred Astaire, Virginia Dale (original, without applause track)
3. LAZY Bing Crosby (film version, with all the background dialogue, SFX and built-in distortions)
4. YOU'RE EASY TO DANCE WITH Fred Astaire (original, without tap SFX or applause track)
5. WHITE CHRISTMAS Bing Crosby, Martha Mears (features an orchestral tag not heard in the film, in lieu of the extended orchestral track that immediately precedes the song in the movie but is NOT heard here)
6. HAPPY HOLIDAY Bing Crosby, Martha Mears (missing the orchestral underscore used for the calendar leader and also the children's track heard over the reprise of the chorus at the end of the song)
7. LET'S START THE NEW YEAR RIGHT Bing Crosby (NOT from the movie or a pre-recording session, but actually a re-recording by Crosby done the same year as the movie - disappointing!)
8. YOU'RE EASY TO DANCE WITH Bob Crosby and his Band (original without audience SFX)
9. ABRAHAM Bing Crosby, Martha Mears (original...but, missing several key lines sung by Louise Beavers, chiefly the line, "When black folks lived in slavery, who was it set the darkie free?" considered racist under today's scrutiny. Also, missing the children's response to the song as sung to them by Beavers as their mother).
10. BE CAREFUL IT'S MY HEART Bing Crosby (derived from the movie soundtrack. Co-star, Walter Abel's prompt to Fred Astaire about discovering the girl he danced with on New Year's Eve is clearly heard under the orchestral prelude)
11. I CAN'T TELL A LIE Fred Astaire (an alternate take of the song with enough authenticity to make it sound original, but missing some of the musical interruptions Crosby stages to foil Astaire's romancing technique in the movie)
12. EASTER PARADE Bing Crosby (original, but, like the others, missing the orchestral 'calendar' tags that immediate precede the song)
13. SAY IT WITH FIRECRACKERS / SONG OF FREEDOM Bing Crosby (original without audience applause track)
14. SAY IT WITH FIRECRACKERS Bob Crosby and his Band (film version, truncated, with firecracker and tap SFX intact)
15. INSTRUMENTAL REPRISE: LET'S START THE NEW YEAR RIGHT, ABRAHAM, BE CAREFUL IT'S MY HEART, EASTER PARADE, YOU'RE EASY TO DANCE WITH, HAPPY HOLIDAY, WHITE CHRISTMAS (missing the Thanksgiving calendar tag at the end and the dower orchestral tag that leads into Crosby having closed the inn to sulk over having lost his girl)
16. I'VE GOT PLENTY TO BE THANKFUL FOR Bing Crosby (a truncated alternate track, minus Crosby's self-deprecating comments to himself, made throughout the song in the movie, and the orchestral tag that follows in which Crosby and Louise Beavers discuss how Crosby will win the Marjorie Reynolds character back)
17. WHITE CHRISTMAS (reprise) Martha Mears (movie version with all the original baked in distortions left in)
18. CLOSING MEDLEY: I'LL CAPTURE YOUR HEART, LET'S START THE NEW YEAR RIGHT Bing Crosby, Fred Astaire, Martha Mears, Virginia Dale (original, without audience SFX).
HOLIDAY INN RADIO PREVIEW: (the tracks below are all from a radio broadcast PR junket to promote the movie and represent highly truncated versions of the score with some dialogue overlap)
