A lot, you are just not aware of it. An album called “Homeless Brother” was fabulous. He never made it big again as with “American Pie,” but he was and remains very talented.
Wonderful baby, Castles in the air, “The Legend of Andrew McCrew” are all fabulous. If you have never heard “wonderful baby” you are missing a beautiful song. Done with the cooperation of Fred Astaire. Here it is: https://www.youtube.com/watch?v=EJJYVJ-Ae6M
