Well, I'm the John Howarth in question. I used to play with Dave Walmisley and Mike Green in Stoneground Band, besides being a BBC cameraman. I remember Susie (see above), and I'm trying to figure out who Ray is (also above).

Heather sang bvs on our Sunstruck album, and I played on Heather's Dingle album, and did some string arrangements as well. Unfortunately I, too. have lost track of her. I can confirm the Whittaker/Whytock combination, but Watts is new to me.
