All kindsof strange info here.
Many dubbers were tested for Nero and Merlino was chosen because his singing voice sounded enough like Neros speaking voice.
Dubbing was mostly not considered for the leads as the vocals were to be recorded live - not prerecorded.
Alfred Newman and Ken darby said this would be nearly impossible, especiallly as the leads were really no singers.
It didn't qjuite qork out that way.
Harris and Redgrave were brought nto the studio, to give the best inflections and interpretations for each song, with a piano recorded on another track.
Once both got the interpretations they thought best, their vocals were thrown away and only the piano track was kept. this track was to used during filming with the vocalists, singing live to the recorded piano that had been used for their vocals.
this would have been tough to do at any time.
Franco Nero was dubbed but he only had two songs - Cest Moi and If Ever I Would Leave You.
So filming starts and these folks can not sing very well to this piano only track.
Sop they shot the songs ni small segments, knowing that they would have to post dub all vocals, once back at the studio.
Indeed, all of the vocals were dubbed onto the piano track to match the fiml, months later.
THEN, Alfred Newman had to match his orchestra to the vocal tracks.
Changes were made along the way. Originally , the song, I loved you once in Silence was to be sung only by Redgrave, Gene Merlino came in to lay in just the Nero tracks for the song months later. When filming this, Redgrave sang live and Nero lip synched !!!
Anyway, alfred Newman and Ken Darby worked for months and months while Alfred had to write the background score - they got an Academy award for it.
Lets hope Warner vid doesn't screw up this soundtrack again !!!!
