I can relate guys!
When you've been playing for 30 years you have a litany of "gigs from Hell! Here's an example.
Used to play a lot of political rallies. (subversive anti Govt. stuff) Standing on the back of a flat bed truck singing "Solidarity Forever" endlessly in the middle of winter, with your fingers virtually frozen stiff from the cold ain't a walk in the park! These days when the local activist groups call, I pass 'em on to younger more idealistic pickers.
