Audlem is near the Cheshire / Shropshire border. The session is at the Shroppie Fly, on the canal, so there are ofte holiday visitors at the session.
Regulars include members of several bands, and a couple of early music groups, as well as lots of singers. I think there's a Rauschpfeife at the Shroppie, too.
Some of the singers are even kind to would-be musicians, and tell them the key. I found that a big help in learning to play by ear, things like "whiskey in the jar" are fairly easy to find.
