shit happens, I know it is really bad form to repeat a song but it does happen and I do get embarrassed for the parties involved, even to the point of not being able to applaud the "repeat" which is probably not good either, however, some may know I sing with two other blokes and last Friday one of em started to sing a song I had sung a 1/2 hour earlier! He got told! Goodness this is way of thread! He had even joined in the chorus and it hadn't registered!
