Save it till after gig. IMO nothing looks worse and more amateurish that the "oh dear" faces when people are playing.
The point being that audience will generally not notice the musical error even if its pretty bad - only your guilty face. I watched a band recently that I used to play in and so know their song pretty intimately was only able to tell they messed up a couple of things by the guilty/accusatory face syndrome.
Sorry to go on a bit but it really gets my goat.[/quote]
Top advice! I see this all the time.
EDIT: In fact, at a gig recently, the vocalist made a miniature speech apologising in advance for a part in the song where his voice almost always breaks... He might have got away with it being intentional if he didn't make this mistake!
