Nearly all of my playing is playing for free and I don't view it as paying to play. I do of course want to get enjoyment out of it which to me is a good atmosphere, no real pressure to perform and fun with the people there - and of course the odd pint of beer helps...I get nothing out of people just listening to me, paid or otherwise - I'm just do it once in a while, usually with someone else as I hate doing that sort of thing alone as I feel too exposed . I just do it for the craic.
