I had the great honour to see Joe Satriani masturbating for 3 hours with some masturbating breaks by Stuart Hamm some 15 to 20 years ago.
They should have called that tour The Creep Show.
Ok, there was a bar, but I don't drink, so we talked very loud for 3 hours with 2 electricity cuts during the show.
And you know who cut it twice : the owner of the venue himself who was the guy who hired him. He said later that he did it because it was a real pain in the *ss.
