Harry Boardman's webpage on FolkNorthWest
has a complete discography. Beltane Song is listed on "A Lancashire Mon" which should be somewhere in the stacks,

Google books has what appears to be the entire Topic catalogue amongst other stuff. Page 179 of The British Folk Revival, 1944-2002 by Michael Brocken shows the track-list for "A Lancashire Mon" (also on the above site).

Can't trace any Bernard Wrigley connection yet (still looking), His "God's Own County" CD (2005) has "Cockerham Devil" listed - I can't remember hearing him do this one.
