Curious how at many sessions the participants want the public to listen to them but won't involve them. Eg 1)they won't play if there isn't anyone else in the pub 2) they won't acknowledge anyone who isn't involved in the session and sit in an inner circle 3) if at 10.45 an interested punter asks for The Hills of Athenry or Grandfather's Clock they look at each other with an amused resignation.
They still want any free food or beer, though!
