Today I was playing at a bar with this group I am in at this music school and I totally ruined I Shot the Sheriff. At the end we were gonna play chorus verse riff chorus then 3 riffs and end it. I went chorus verse then into the 3 riffs, so when everyone else went into the chorus I played the riff again and screwed everyone up. I always thought my ability would be the only thing to hold me back at any point, but now I am forgetting simple song structures. Needless to say it totally fell apart and although most of the crowd didn't know whose fault it was everyone playing did!!! At least most of them I think thought it was funny because none of us wanted to play it. Has anyone else ever done this and turned a solid song into a train wreck?.....by the way the second song was good, although I lost some confidence!!!
