"I take Jim's point that it might be nice to be able to tell in advance what to expect but I don't think that will ever happen: some battles are already lost."
it happens all the time when there is a guest booked, if martin carthy is booked you know what you will get.
The problem is singers nights, but if you got to clubs with decent residents like the wilsons club in billingham you know you will get a high standard of singing,
IN OTHER WORDS IF IT IS A SINGERS NIGHT FIND OUT ABOUT THE RESIDENT SINGERS.
