The Maid of the Sweet Brown Knowe is the English version of a tradfitional, lively Sean Nos tune. I don't know the Gaelic version, although I have heard Aine sing it.

The English version starts:

Com\e all ye lads and lassies
And listen to me a while
I'll sing to you a verse or two,
'T will cause you all to smile
It's about a fair young maiden,
And I'm going to tell you now
How she turned away a suitor
At the foot of the sweet brown knowe.

It can be a reg'lar toe-tapper, done right.
