I seem to be writing mostly about Bettakultcha at the moment! Just to add that if any local folk like the sound of the Bradford session I went to, there will be another at the same venue on 11 August.
There was an incident at the recent Leeds event which is a challenge for the format; I suppose it is to some extent inevitable that problems may occur given that there are no rules other than “no pitches”. I wasn’t there so haven’t weighed in with comments. Find out more via this blog post by the organisers and lots of comments and debate from the people who were at the event.
