You could try 'The Bash' at the King Billy in Cottingham each Sunday from 8.30pm. This is an open mic night rather than a session but would give you chance to meet other musicians. It's not a folk night as such though folk music is played there along with bits of everything else.

Yes, I know I've posted this on the other thread as well. It's my shameless exploitation of this publicity medium.
