Dan:
it all depends who is there. When I see the names of who is leading the sessiun (in their ad in the Emigrant every week) I might go based on that; but then they switch often enough, too! If I know a friendly face who I know won't mind a song or two (or who I know will almost always ask me to sing one) I will stop in with my boudhran and play and hope to do a song or two. If I am just stopping in for a drink I feel comfortable enough with some musicians to ask if I can do a song...depends on the vibe...more and more lately there are lots of younger musicians there I don't know (lots of fiddles!) and in those cases it is very "tune" oriented...

Mondays is always Johnny O'Leary and Vinny Costello leading the dance tunes, both great guys and Vinny sings a few songs himself...other days of the week it varies with who is there...

cheers,
