Also reminds me of the Olympics, our sax player's band was offered a jazz spot by the Olympics organisers as part of the festival, but they weren't to be paid (he's a professional sax player).  The benefit of playing to a good crowd, being part of the Olympics was to be enough.  He said 'no'. 
 
Were the doormen, bar staff, cleaners, technicians also doing it for nothing?  I doubt it. 
 
Had a similar thing in the Motown band, a charity do, we were asked to do it for half price.  We did, good cause and all that.  No food (had to go to a local pub for some grub), nowhere to get changed.  Were the bar staff and anyone else paid half?  Of course not.  Did the band get thanked for our £600 contribution to the charity?  No.  It was made clear that we could have one non-alcoholic drink from the bar and we were asked to hurry to clear away so the staff could go home.  I was not my normally cheerful giver that night. 
 
Ok, rant over.

I've noticed that alot of places and people treat live music as a bit of an 'extra'. They don't see the musicians as professionals, even if they do it for a living, so people get a bit indignant when they find out they are expected to pay them as they would bar staff and caterers.
