This was the first folk song I ever heard and tried to join in on, 'twas at the Buck Inn at Malham in 1970 when I was on a two-week botany field course at Malham Tarn. We got the words more or less right but everyone deliberately slurred "dabtoes" as none of us knew what the word actually was, let alone what it meant! Actually, recalling my usual condition during those pub evenings, I probably slurred all the words...

And I've probably forgotten more than you'll ever know about clints and grykes!
