I imagine a certain generation of Yanks (I include myself) first heard of this song via a 50s recording by Richard Dyer-Bennet, no doubt suffering from folk attrition and perhaps D-B's rewrite for propriety or other reasons. Still, I did learn this from him (along with my first reasonably difficult guitar licks), and it's interesting to speculate where and how he got his variant. This is, verbatim, how the liner notes to the record had it:

LITTLE PIGS

Little pigs lie on the best of straw,
With an oink, snore, oink, snore, oink, she nan little dog. (repeat couplet)

Cho:   Lillie bolay, oh lillie bolay, oh lilly bolay, oh lilly bolay,
            Oh, my daddy's a bonny wee man.
            With an oink, snore, oink, snore, oink, she nan little dog.

Little pigs maketh the best of pork,
With an oink...


That's all there was to it. "Lillie bolay" = Lilliburlet or equavalent, "bonny wee man = "funniful/funicle" man, "she nan little dog" = "shan diddle dong" I guess.

By the way, what's "funicle" mean? Certainly not funicular??? My daddy's an elevated railroad? Oh, my sainted aunt, as Mr. Campion would say. No, I'm not seriously proposing that. Scratch it. (It itches.)
