Mudcat's Dr John has also given the address on the thread on Black Country Songs.
Correspondence with Mike Raven is always rewarding, he comes across as a mix of Laurie Lee, Rick Fielding and Carla Lane.
(If anyone doesn't know, Mike had youthful brushes with the law over his animal rights activities, many of his songs celebrate the fox and his own dogs. As a young man he bummed around Spain learning from gypsy flamenco players and reviewers describe his folkplaying as Celtic Flamenco. He is always generous with his knowledge. Purchases from him often contain extra free songbooks or records.)Mike used to have a web page but it seems to be inactive.
