I have the same 45 plus one with the music from Shoot the Piano Player. Bought them in a record store in Greenwich Village in (I think) 1966.
I'm sure you'd enjoy the Nonesuch recording. It covers Delerue's music from a range of Truffaut films.
Lew Chudd who owned Imperial Records supposedly had Fats Domino's records speeded up to make them more commercial. Seemed to work for him and for Fats.
