Question of authorship.

The song has apparently only been recorded by The Spinners and a number of Scottish pipe bands, who seem to have got hold of the tune and decided they like it.

The British Library (Cadensa) attributes it to Trad. in the Spinners' recordings but I can't find it elsewhere, neither in broadsides nor in the various ballad indexes.

Is it another of Hughie Jones' masterpieces (like Ellen Vannin) or is it truly traditional?

Cheers!
