Paddy Tunney learned that set from Paddy Doran (see Paddy Tunney, The Stone Fiddle. Dublin: Gilgert Dalton, 1979, 108-9). That means that my guess at Bert Lloyd's source, made six years back, was wrong; unless Mary Doran's set was very different from Paddy's.

On the whole, it seems more likely that the version popularised by so many Revival singers derives instead from Winnie Ryan of Belfast, who was recorded by Peter Kennedy and Sean O'Boyle in 1952. Her tune is much as the one now familiar, though the words have changed somewhat. If Bert Lloyd had a hand in it, though, that wouldn't be too surprising.

The Altan recording Philippa referred to a couple of messages (and 3 years) ago is precisely the Revival tune and text: they name their immediate source (Gráinne Nic Mhaonagail from Dobhir, Gaoth Dobhar, Donegal), but add "The song was collected in Co. Wexford from a traveller". Without specifics that isn't much help, and doesn't preclude Gráinne's having learned it from standard Revival sources while being vaguely aware that it came from a Traveller.

The Clancys got a lot of their songs from the folk clubs rather than directly from tradition, so I'd expect Liam's recording to be of the standard type as well; though, since I don't recall having heard it, that is mere speculation.
