I don't want to attract anymore hostility BUT let me expand on my original posting. What is a performance ? Somebody singing a song? Right, let's run with that! Somebody gets up and sings a song that they've learnt from a recording or whatever. Now, I would hope that they - if talented - even just a bit, would want to bring something to themselves to that song. Now, if they can bring something very different to that song - and it works -then, that to me, is very interesting, and worthwhile. Take, James Taylor. He has the knack of transforming well-known songs with a different chord here and there, or a change of tempo or feel. This level musical sensitivity is, I'm afraid, a rare commodity. What for you would fit into that category!
