Hello all - I'm trying to learn The Young Tradition's version of 'John Barleycorn', but I'm a bit stumped by the chorus;

To my ears, they sing:

Fol-a-dol the diddy-ey
Fol-the-dol a diddy-aye (go on? Grow up?)

I'm sure, however, that this isn't quite correct - can anyone confidently share an accurate wording?

Here's a link:

Thanks in advance!!
