I have the Beggar's Velvet CD too, title track "My Lady of Autumn", which may help you find it: another of many good songs all on that one CD. I also like Ossian's version.

A friend has recently started singing it, but has so many variations in the tune that I asked where she'd got it from: another artist not so far mentioned, who was presumably "making the song my own" - but it does make it difficult to join in or accompany when it wanders so much from the usual tune! She wa quite surprised when we played her the Ossian version.
