Thanks, Nic. Diolch fawr for the Flickr reference, as goonligg "Sain" and seeking cool covers came up nearly empty, to my surprise, and I figured somebody out there must've archived them. I wish I could read Welsh to understand the Y Lolfa-published account of the label. By the way, the only way I read Hill's book was by interlibrary loan. My librarian certainly did a double take at the title!
