I would be surprised if they had. That’s actually one of the things that really bugs me. You often see people putting on events, and advertising for bands and musicians to play; usually for free, or for the ‘exposure’. Yet they’re quite willing and expect to pay everyone else, security, bar staff, waiters, kitchen staff etc. I’m not being at all precious, but I have two degrees in music, whatever I can do is the result of god knows how many hours of practicing, yet I’d still at many events, be expected to give my services for nothing.
