I certainly don't have to mention this to the informed participants of this discussion thread but the first 5 LUCY-DESI hour long presentations were originally aired as infrequent tv specials throughout the 1957-58 television season on CBS.
The remaining 8 hour long segments were originally part of the (WESTINGHOUSE) DESILU PLAYHOUSE (CBS 1958-60) anthology tv series cataloque.
This is a complete title listing of all 13 LUCY-DESI COMEDY HOUR episodes:
01) "Lucy Takes a Cruise to Havana" (06/11/1957)
02) "The Celebrity Next Door" (03/12/1957)
03) "Lucy Hunts Uranium" (03/01/1958)
04) "Lucy Wins a Racehorse" (03/02/1958)
05) "Lucy Goes to Sun Valley" (14/04/1958)
(WESTINGHOUSE) DESILU PLAYHOUSE
First Season (1958-59)
06) "Lucy Goes to Mexico" (06/10/1958)
07) "Lucy Makes Room for Daddy" (01/12/1958)
08) "Lucy Goes to Alaska" (09/02/1959)

The generic moniker THE LUCY-DESI COMEDY HOUR is actually this collective group of presentations' later summer repeat airings (on CBS) and tv syndication title.
