Note: Sorry for the less-than-stellar quality of this upload. It is taken from a 1930's sheet music version which belonged to my father. He was an amateur trombone enthusiast who played through his army and college years. As I remember him telling me, he played the B-flat version, and was glad when the A's came out nicely!
