I always found that playing in Legions the best venues to play. Sure they drink and get loud but they love the music and it is a safe place to play. In most Legions they watch t.v. and have been asked if I mind if the t.v. is left on so the folks can watch the hockey game. I always said no problem, just turn the sound down and they do so.
Pubs/Bars are a bit different than a Legion so I say again that the musician should really check the place out before hand.
