There was also a piano/vocal sheet of a theme from VIVA MARIA available at one time. The theme that Bardot and Moreau sang in the film. I seem to remember reading that Leroy Holmes had something to do with it. I'm not at home at the moment, so I can't add a publisher's name, though I kind of think it was UNART.
And also, I have done a couple of piano solo arrangements of my own of two Delerue themes.
One is the Generique from VIVA MARIA and the other is the Pavanne from KING OF HEARTS. They are the best I could do by ear (I did not have access to the scores). I would be willing to share them with any other keyboardists.They were created with MuseScore and I have them saved as PDF files. If you are interested, contact me for a free copy.
