Peter Bellamy was really getting into Ulster singers when he used to sing at our folk club at the Eagle Tavern in NYC. His version of the song (called "Down the Moor," as I recall) was from another Northern singer. I don't recall whether it was Eddie Butcher or Geordie Hanna.

They are both great song versions. Try to make your strumming hand work in close concert with you vocal phrasing regardless which you pick. It seems to work well.

All the best,
