I speak only from limited experience, but when go to local clubs and singarounds I'm almost always the youngest person there, and I'm no youth at 38. I've found the standard of singing to be fairly poor overall, forgetting words seems to be the norm rather than the exception, but the spirit is usually positive and friendly. It's the singers who only seem to know 3 or 4 songs that put me off, they sing the same bloody songs week in week out.
