Ghosthouse, jazz musicians depended more on record sales than concert tours. I forgot what the ticket prices were, but this wasn't a stadium; jazz musicians depended on record sales, and although records were selling, the musicians didn't seem to reap the benefits. Now there are local musicians who record, and sell their own CD's; they're living at about the same level as someone with a good job; nice house, new car; they are not hurting.
Maybe Frogman will chime in and enlighten us; we're not talking about musicians with big dope habits who could make any amount of money and still be broke.
Enjoy the music.
