Who Is Harry Kellerman and Why Is He Saying Those Terrible Things About Me? (1971)

Poor Georgie. One day Georgie Soloway jumped off a penthouse, fell in love in an empty theater, raced down a ski slope, circled Manhattan in his private plane, and tried to find some creep who put him down to every girl he liked.

A hit pop songwriter, who cannot love himself or others, spends his days with various women flying his plane, and dropping in to the world around him.
