At the very start of the Dubliners’ version, Ronnie Drew wryly observes “We’re only allowed to sing five of them.”
Yeah, no kidding on the folk songs. A friend of mine gave me a mix tape of Scottish folk songs by Jean Redpath. One of them, “A Wee Bird Cam’ Tae My Apron”, is about a young woman who goes down to the pasture to tend her father’s cattle and encounters a “wee bird”. When her mother and father ask her about the lump under her apron, she tells them it was given her by “the best stay-makar, in the toon./And he’s made me a stomacher [undergarment] tae bear up my goon [gown]/And he’s rowt it beneath/my apron.”
Didn’t need to translate much of the Scots to figure out what that song was about.
