This soundtrack has a lot of problems. The original UA audio was poor and not until a Spanish LP came out did it have full, vibrant audio. So if anyone has put that album on CD, that's the one to get. I'm sticking with the LP. As for the extra tracks, aside from the bootlegged Marilyn tracks like "Diamonds", I think most of them are from the companion LP SOME LIKE IT HOT CHA CHA, which are studio recordings of songs and themes from the picture in Cha-Cha as played by Sweet Sue's band.
