I was a follower back in the day, booking them for my folk club in Cardiff. I have both their LPs.

The album mentioned above is from 1976 on Avada Record f Cheltenham.
Their eponymous RCA album (1975) lists musicians as Paul Cobbold, Stuart Gordon, Pick Withers, Phil Harrison and Vick Smith.

They may have worked as a larger unit but I only ever saw them as a duo.
