+1 to going nuts and not giving a .....
Last show we did a cover of For Whom The Bell Tolls (because the crowd always loves that shit). I do an improv thing at the end where kirk does some weird trem shit on the record. Lost my place about halfway through it because I was flailing about like a madman. No one noticed because I really was as into it as I seemed to be.
I had more fun playing that than any of our originals because EVERYONE was into it, I was into it, and it was fun as shit despite the .... up.
So...relax and enjoy! +1 to the rehearsing EVERYTHING down to the detail though.
