I am struck by the similarity, in metrical structure, if not in tune, between O, WE'RE A' NODDIN AT OUR HOUSE AT HAME (in all its variations):

O, we're a' noddin, nid, nid, nodding,
O we're a' noddin at our house at hame.

--and WE'RE ALL DODGING:

For we're all dodgin', dodge, dodge, dodgin',
Yes, we're all dodgin' our way through the world.

Can anyone tell me whether there's a similarity in tunes? (Being a non-musician, I am relatively handicapped in this area.)
