Hi Guest. You are spot on with your comment "I've also noticed that some of the pre arranged opening spots at certain folk clubs also seem to have the Open Mic mentality and will often leave just after their sets and not even listen to the main guest. However, resident singers and musicians are very unlikely to do that as they know the score and respect other performers.

It's not so much the support or floor singer not staying, but its the dozen mates who came to hear them walking out too. "

Sometimes the organisers leave the room when floor singers are on.
