Poor Butterfly was written by Raymond Hubbell and John Golden. The St. Louis Blues was written by W.C. Handy. In Poor Butterfly, Fats makes the piano sound at times like it is gently swaying in a breeze. In The St. Louis Blues, Fats creates new riffs from the song on some bars and borrows a few riffs from George Gershwin along the way.
