Charles Mingus and Charlie Parker had been talking for a while now backstage just before the concert which would take place at the underground cavern in Chicago. They were discussing Zen and the principles of Buddhism. Arguments and explanations came fast from both sides. Charlie "the Bird" Parker was in the middle of explaining a concept to Mingus when the two musicians were interrupted by the Club owner who informed them that it was time to get on the stage and play.
- "Let's continue our discussion on the bandstand" said Bird.
