There's one verse I don't understand.

So after rejecting all her gifts, Alison's finally blown her horn and turned our reluctant leman into a poor old worm, and so now he's crawling around the tree.

Then there's this verse (right before Halloween when the Selie Court ride by & he's changed back again):

"Wi silver basin an silver kaim
Tae kaim my headie upon her knee,
Aye on ilka Saturday nicht
Aul Alison Gross she comes tae me."

What's that mean?
