Sorry. Posted too soon.

Though we share things, we seldom use song books etc. People start off by joining in the chorus and after a few times round we find we've got a shared repertoire.

Not really sure I like the idea of going to a session where everybody's handing round sheets all the time. I think that's one major difference across the atlantic. Believe me, people learn very quickly without books and things (or photocopied sheets).
