Thanks Bob!
I presume that the Mike and Reina Sutcliffe I need info on, are English - but I have NO evidence to support that!!

Mary Hopkin chose to record the song "Water, Paper and Clay" (copywrite with Essex) on her 1971 Apple album "Earth Song, Ocean Song", simply because she "liked it very much", but I don't know from where she obtained it.

Curiously, the only other reference I can find to it, is on a South Australian recording by Judith Crossley (apparently available via Folktrax) - she of the "Coonawarra Has 3 Shadows" fame!!

So, you never know ...

Cheers! R-J
