There are at least two official Old Timey sessions listed in the festival programme. IE.,

Tuesday, 1-3 Rattle on The Stovepipe will be playing with Joe Locker in the (oh God!) Conservative club bar.
Friday. 1-3. The New Deal String Band, Pete Cooper and Dan Stewart are in the Fisherman's Rowing Club.

Both events are free, and of course you don't HAVE to buy any refreshments in The Con Club. Last year we ended up singing the Internationale and The Freedom Come All Ye in there.

Plus of course both bands will be playing at various other paying venues around the town.
