When I had the day Job , I could afford to do quite a few festivals IF I could get the Friday afternoon / monday morning off - Now that Music is my main income , and more than enough gigs are on a friday or saturday , it means that I dont get to so many - UNLESS I am being paid , and if i am NOT working , it works out a bit expensive ! Catch 22 strikes again !
For me , its as much Sessions as guests that get me to a festival though
