During the early 60s Bob and carol Pegg were involved with 'Folk studies' at the University in Leeds.

They also ran the 'Yorkshire Folk centre' folk club

Bit too purist for me during those days

Maddy Prior may be able to throw some light on the subject as she did a floor spot and secured a gig I do believe.

Give Malcolm at the Vaughan Willy mem lib a call first, I used to go there during my free periods and lunch break from work.

all the best with your work
