I recall reading in a Zappa bio that when the union found out (just before the band went on) that a show was being recorded for radio and TV, the union rep demanded their scale for broadcast work, instead of performance/sound reinforcement. It was $9000 EACH extra from Zappa, the radio, and the TV people ($27,000), or they would pull the plug. They got the money, but that is why Zappa refused to play in NY for many years.
As for live Blue Notes, I recently purchased Donald Byrd at the Half Note.
