Nice bit of self promotion Dick (I think!!) - not sure of your point, but at least no-one can accuse you of being backward about coming forward!
spot on, Jim, my point is that you can ascertain what kind of folk music from seeing who is advertised, if you saw jim mcfarlane you would know that you were going to get irish unaccompanied folk songs, martin carthy trad songs with guitar, leon rosselson contemporary songs with guitar, so what it say on the tin you are going to get.
   singers nights, are of course different,incidentally the i can think of only two singers who occasionally include fifties pop songs that is andy caven and dave burland, dave, does include trad songs too.
