The Bakewell session where they "frowned on you if you didn't play in that night's chosen key" was an Old Time session where the fiddlers and banjo players have to re-tune their instruments to change key and keep the right sound. This session is now on a Thursday night in the Queens Arms. They mostly play fiddle tunes, with a few songs, all American Old Time. Everyone's welcome if you stick to those rules! There is no difficulty with staying in one key as the participants could play for a week without repeating themselves....
