It is quite similar to Carthy's text, from memory.

That verse doesn't seem to be present in some of the texts in the Bodleian Ballad Library (Sylvia's request and William's denial) which all seem to be pretty much identical.

It is interesting (to me, at least) that there is an apparently earlier song called "Roger's request and Sylvia's denial", but there is no hint of a highwayman in that one.

PS. I am still puzzled by the Bodley listing the song under the subject Transvestism, rather than (perhaps) disguise!
