The radio shows required 25 minutes of music. Each week Harald would take his tape recorder to Memorial Presbyterian Church and start playing. He would be watching the clock and when the end was approaching, most of the time he improvised to fill out the time. The (numbers were arbitrarily assigned by the University of Alabama. They are included here so that you may sit around with friends and say things like "I really like the Improvisation on Tape 128" and your friend can reply "Nah, the one on Tape144 is the best!!"
