They were called "yr hwntws" and were from South Wales. I have one of their albums on vinyl: it is merely called "yr hwntws" and is on Loco #1001. It was released in 1982. The contact is Mike Lease from Coed Eva, Cwmbran. It gives his address on the sleeve as 194 Oaksford, Coed Eva. (After all this time he has probably moved on).

I think I heard of them due to a local radio folk programme! They were great!
