"The Erotic Muse" by Ed Cray was Oak Publications, not Dover. Published in the late '60s. The revised and muchly expanded second edition from The University of Illinois Press was published in 1992.

I don't know if Ewan MacColl's multi-LP (early '60s, I think) edition of Robert Burns' Merry Muses of Caledonia is available. There is a CD by Davy Steele, Robin Laing et al of the Merry Muses with some good material but some strange tunes on it (especially the tune for "Nine Inch will Please a Lady" -- haven't a clue where they got it). Jean Redpath did include Burns' bawdy stuff on her multi-volume set.

Look up Frankie Armstrong's recordings, too. She's my source for "Nine Times a Night" and "Too Much of a Good Thing" among others.

"The Bird in the Bush" with Anne Briggs, Lou Killen, Bert Lloyd, Frankie Armstrong & Norman Kennedy is available on CD, but I don't think Arthur Argo's "A Wee Thread o' Blue" is.

Then there's www.armadillo.net/llewtrah/songbook.html -- Llewtrah's bawdy songbook. She's a collector of rugby songs as well as other bawdry.

Or PM me and call me and I'll sing stuff to you.
