Hi Early , the whole idea of a fringe is that it is spontaneous and unorganised. If the festival committee (bless them all for their stalwart efforts) were to take over the fringe it wouldn't be a fringe but an organised event. The fringe tales place normally in the Middle Earth, Fleece, Endeavour (evenings only) Black Horse, Tap and Spile, Elinsor and the Ship at least. There is also Glaisdale Sunday when I good few of us take the train to Glaisdale for a session in the Arncliffe Arms at lunchtime, train out 12:43 train back 4:30
Cheers
