Belafonte included this song on one of his recording of folksongs. I'm not certain it's considered folk by folkies though. I couldn't find it in the digitrad, so it may not be. Anyway, the only lyrics I know are:

Go way from my window
Go way from my door
Go way, way from my bedside
And bother me no more, and bother me no more.

I was reminded of this song because someone started a thread about favorite celtic songs that he wanted to arrange for a sextette. I realize it is not Celtic, but I have heard a beautiful choral arrangement of this song, an it might do for him.
