Guest Lin, I was able to purchase some of the cds I was missing from John's widow a year or two ago. If you search for the website ,(sorry I can't give you details at the moment, but shall when I get to.pc if no-one else does so meantime). There were certainly some still available then? Barbara posted them to me.
He was an amazing performer, chose really wonderful sings and delivered them from the depths of his soul.
Still greatly missed.
