I wouldn't know. I haven't heard her singing it. I'm only aware of one tune to this particular Farewell (oh, and I should have written "Ffarwel" with an accute accent on the "e") so I suppose it's the same one. I think it's in the Dorian mode...

We had a presentation on the Welsh songs of Farewell at the last Welsh Folk Song Society weekend - there seems to be bucket-loads of 'em.
