Michael Raven (link above) used to be in the Black Country Three. A 'best of' is now available direct from Michael, which includes various black country songs. The Boxing Match certainly refers to Wednesbury.

BTW, "Can't find Brummagem" is in Roy Palmer's 'A Touch on the Times.' To be truly pedantic, Brummagem isn't the old name for Birmingham, merely a corruption, as with "Lunnon" for London or "Glasgae" for Glasgow...
