Possibly germane to the thread:-

there was a Mike and Julia Billington folk agency back in the 1970's (I think). They were located (I think) in Astwood Bank, just outside Redditch and they advertised in Joe Smith's folk diary.

As I remember they did some gigs for Alex Campbell and maybe Derek brimstone. Certainly they did some gigs for a very good guitarist who was around at the time called Dan Fone. Dan used to travel round a bit with Alex and the last time I saw him was on telly playing with Ricky Cool and the Icebergs.

All of which tells me, that perhaps the place to look is any remainders of the Black Country folkscene - maybe Taff Thomas, who had a club in Coseley. Tim Laycock was in Magic Lantern with Taff.
