The performance is everything on all levels and for all reasons, you have a duty to the paying public to be at the best of your ability and , not to be confused with EGO, self esteem, no one is happy with themselves if they perform badly, that's why I feel embarrassed. When the three of us are singing together and something doesn't sound right I always blame myself, which isn't always the case. A case in question , we were asked to sing at a remembrance day service , Ron dropped out a week before, so Martin and I did it, the specific songs requested were all songs that Ron lead and we hastily re-arranged them. As we were stepping on to the stage Martin confided that he had moved the key up half a note on his song, I was apoplectic, as someone who relies a lot on muscle memory it was a disaster in the making, I actually made it through his song and screwed my own up, I dried half way through, and as in a folk club, cracked a joke about it, i think everyone laughed, but I was mortified that it was wholly inappropriate at that type of event.
