Tull *is* folk, to me!

Has anyone put Up The Airy Mountain to music? I don't know the author, but here is as much of the peom as I recall:>p>Up the airy mountain, down the rushy glen
We daren't go a-hunting for fear of little men
Wee folk, good folk, trouping all together
green jacket, red cap, and white owl's feather.

They stole little Bridget for seven years long
When she came back down again, all her friends were gone
They took her lightly back, between the night and morrow
They thought she was fast asleep but she was dead with sorrow
They have kept her ever since, deep within the lake
On a bed of flagweed, watching till she wakes.

Up the airy mountain...

Sigh, such a sad, sad poem, but then, that's the Little Poeple for you.
