GODFATHER PT ONE

In Godfather 1 Hagen (DUVAL) is sent to CALIF. We hear the song "MANHATTAN SERENADE"which was never released on the sound track. On MOB HITS 2 the song pops up performed by
T. Dorsey & Jo Stafford. This is not the version used in the film.
The film version sounds as if it was recorded when the film was made, not a 1940's recording which is on mob hits 2. Who is performing "Manhattan Serenade" in Godfather 1 and is THIS version available?
