I noted Arthur Argo's recording in my post above, Prestige-International 13048. Here's a bit more info:

I forgot to mention another rather rare 1950's collection of bawdy songs, Mack McCormick's field recordings on 'The Unexpurgated Songs of Men", stated to been recorded in Texas in 1959 and copyrighted in 1960. (No record label or id# given). Contents (not all are songs): The Ring-a-Rang-a-Roo/ The Keeper of the Eddystone Light [DT and Bodley Ballads- The man at the Nore]/ Mamie had a Baby/ Cocaine Bill and Morphine Sue/ Take a Whiff on me/ The Bastard King of England/ No Balls at All/ Barnacle Bill the Sailor/ Big Jim Folsom/ Cristofo Columbo/ The Monk of Priory Hall/ The Hootchy Kootchy Dance/ Always in the Hallway/ The Merry Cuckold/ In Crawled One-Hung Lo/ Who Stole My Beer/ Dicky Dido/ You be Kind to Me/ Boar Hog Blues/ Grubbing Hoe/ Uncle Bud/ The Girl I Left Behind Me/ There's a 'skeeter/ You Got Good Business/ The Dirty Dozens/ (Limericks)/ The Ball of Kirriemuir/ Change the Name of Arkansas [a monologue].

Compare texts of Oscar Brand's versions of songs to real traditional versions on McCormick's recording or in Ed Cray's The Erotic Muse and you'll see how badly expurgated Brand's versions were. Brand published 41 of his texts and tunes in his book Bawdy Songs and Backroom Ballads, which, of course, he copyrighted (1960). As far as I'm concerned Oscar Brand's songs are Brand songs, not folk songs.

Does anyone have volume 2 of Brand's recordings 'Bawdy Songs and Backroom Ballads'? I would very much like to see Brand's text of "A Gob is a Slob"? He is said to have collected it from a sailor in Galveston, Texas. His expurgated version, "A Guy is a Guy" (I walked down the street like a good girl should) became a top hit of 1952, sung by Doris Day. His original (which I doubt we'll ever see) is a descendent of one which of which there is a fragment in the Percy Folio MS (c 1643). The Percy folio text and several later English and Scots versions are given under "Dainty Duck" in the Scarce Songs 1 file on my website (www.erols.com/olsonw).

I had seen it stated about 30 years ago, I've forgotten where or by whom, that songs in Pills to Purge Melancholy were somewhat expurgated. Since that was the biggest collection of bawdy songs that I knew of at the time, I thought that the statement was ridiculous. Later, after having seen earlier drollery and manuscript versions of many of the songs in Pills, I was forced to agree with the statement.

There are other old recordings of bawdy material that have little to do with folk songs. Martyn Green's mad a recording which included many bawdy 'Limericks' [I was late to discover that there were some Limericks that weren't bawdy], Rusty Warren's 'Songs for Sinners', and "The Flutterblast [farting] Contest", for example.
