From the same 1972 episode of The David Frost Show as this clip, we have Stephen Sondheim performing a song of his called "Boy, Can That Boy Foxtrot." It was written for Follies but was cut and replaced by "I'm Still Here." Like most of Mr. Sondheim's discards, it had a considerable life after death. It turned up in several revues of his work — most notably in Side By Side By Sondheim, and Nathan Lane sang it in the movie, The Birdcage.
Here's a young S. Sondheim performing it…and proving the old adage that most composers would never hire anyone who sang their songs as poorly as they themselves do.
