Thanks Lesley, I think I've got it, but was to lazy to look it up. I have other pressing business at present. One item of which is to do a review of Steve Roud's indexes (where I've pointed out that it's the most extensive bibliography of folk song sources I've ever seen) combined with one on the Bodley Ballads website for 'Folk Music Journal'. {Mike Heaney, who was the leader of the Bodley Ballads project, is also editor of FMJ.)
