I rang him about 5 years ago, found his telephone number in the Wolverhampton area, more in hope but was right first time. He suffered from Parkinson's. He gave permission for non-commercial use of one of his songs. I would think he would have been overjoyed to represent Wolverhampton in music - owr kid.

Did he register the particular song with PRS?

there are 2 Wolverhampton Ravens in BT Directories might they be related?

One son (D) might be one of those.
