Thanks! I knew there was some controversy about this, hence my "supposedly", since the play was publicised at the time as a work or improvisation, but I didn't have access to exact information about this.

For the record, there's nothing (or at least very little) that's improvised about Jack Gelber's dialogue in The Connection; if you check the play as published, it matches the dialogue used in the film. I saw the Living Theatre's amazing original production three times, and the speeches were the same each time around; only the jazz solos were different. Jonathan Rosenbaum
