You might find some useful info at one or more of the following links:-
Tyke's News - West Yorkshire
filofolk - a Folk diary connected to Tyke's News - Just a small note - Both the links to September and October bring up a page headed "October" but the contents are different. I suspect an unspotted typing error on one of the months.
South Yorkshire Folk and their Diary which also mentions some events further afield.
Stirrings magazine (South Yorkshire)and their Summer 2010 Diary.
Quack!
