Jeaannie Robertson actually sang the chorus of that one, IIRC, as

To me roving eye
Fol-a-diddle-die
To me roveing fol-de-daddy
To me roving eye.

But there are, of course, probably variants with the ricky-doo-dum chorus. I recall a sleevenote somewhere ~ in one of MacColl's or Lloyd's records ~ referring to a variant of one of the songs as sung to "the Ricky-doo-dah tune", by which he obviously means The Keach In The Creel, which he expects to be familiar to all his readers/listeners with that chorus.
