What's new Pussycat. Burt Bacharach

Michael James (Peter O'Toole), a notorious womanizer, desperately wants to be faithful to his fiancée Carole (Romy Schneider), but runs into serious problems since every woman he meets seems to fall in love with him. His psychoanalyst Dr. Fassbender (Peter Sellers) can't help him either since he's busy courting one of his patients who in turn longs for Michael. A catastrophe appears on the horizon as all the characters check into the Chateau Chantelle hotel for the weekend not knowing of each other's presence.

This famous theme was written by Burt Bacharach for Peter Sellers' character. "It was an instrumental first and then words were put on it. If it's got a good melody it can always fit the lyric, I think if you've got a theme like this and the music comes from watching Peter Sellers and his craziness in that movie and you're trying to make it that way and out words to it".
