Sessions are on my Twitter page. I won't be at Bells on the Sunday afternoon - on my way to Bosnia - but the rest of the usual crowd should be there. It's usually good on holiday weekends. Wednesday night there is a session at the Diggers (Athletic Arms) in Dalry/Armillan, which I haven't been to (too hard to get back home from) - it's associated with the Scots Music Group out there and they play their repertoire.

Friday night at Bells can be lively (mostly Irish tunes, some Scottish and other), though I'm not there often. There may be some bluegrass session that Friday in Edinburgh or acoustic/Americana one in Midlothian, but I don't know yet.
