I think most people who get as far as halfway serious about what they are doing do try to vary it.

I was once introduced when singing in a break in the dancing at a ceilidh "This is RIchard, he's one of our singers, we don't know what he's going to do, in fact I don't think we've ever heard him sing the same song twice".

One Knockholt, with the aid of songboooks, I played pretty well all the time I was awake from Thursday to Saturday night without repeating myself.

Over the winter song sessions I have run in my local pub, I think I have only repeated myself once, and that was by request.


Not that I'm like the late Carey Roberts, who had thousands of songs in his memory, but I think it's worth avoiding sameness, and I think most people do try to.
