There are 2 versions of this in Wilf Moorman's Yorkshire Dialect Verse, the one being collected locally and the second one as published by Robert Burns (who collected quite a lot of English material for various publications). There are also some useful notes in this excellent publication. The Knaresborough version of "Flowers of The Forest" (as performed by The Watersons) is also published on this site.

Cheers!
