A few months ago I wondered what was the first movie to license a musical recording. I thought it might be the recording of Rudy Vallee in Margie (1946). (Though I'm still not sure if they used a real '20s recording of Vallee or just had Vallee re-record the song. But still, it was an attempt to at least sound like they were playing a real '20s recording by a real recording artist of the era.)
But then I saw the goofy 1945 Arabian-nights parody movie A Thousand and One Nights -- a very silly but fun movie with Cornel Wilde as Aladdin, Phil Silvers as his sidekick, and Evelyn Keyes pre-dating Barbara Eden as a magic genie with a crush on her master. The movie, which is full of deliberately anachronistic references, ends with Keyes doing Silvers a favor by turning him into Frank Sinatra, singing "All Or Nothing At All" for a harem of bobby-soxers. (Yes, everybody did this gag in the '40s, even live-action films.) I don't have Sinatra's own recording of "All Or Nothing At All," his first big hit, so my questions are:
1) Is that Sinatra singing, or an imitator?
2) If it is Sinatra, is that his actual recording of "All or Nothing At All," or is it a re-recording?
Update: Via comments, the answer is # 2, a Sinatra re-recording made at Silvers' request.
