This is, of course, yet another of those threads that doesn't have a right/wrong answer.

Many songers, myself included, are only too happy when people recognise a song for them to join in the chorus:and I accpet that repeated lines in ballads do not always constitute a chorus and should usually be left alone.

As a solo singer, I don't mind if anyone with a good harmony tags along on the verses. I will admit that, very occasionally,an auduence can highjack a chorus cos the version that they sing locally is different from mine and that can throw you a bit, but overall I'd rather have the buzz of an audience singing along.

Now that won't suit everyone, so maybe the answer is for people like me to invite participation rather than for the audience to assume that its ok. But if it does happen to you, it's fairly safe to assume that the audience is singing along out of pleasure with your performance and your choice of song, and accept the compliment.

P.S. Jim, L.K. is one of the most nicest singers that you could wish to meet, and no visiting singer would anything less than total respect at her club.
