Maelgwyn,
The version in the DT is the one I sing. Some of it remembered from childhood and some, I think, based on Dan Mulner's (Liam's Brother!) book "Bonny Bunch of Roses".
There are variations around alright - rather than particularly different versions. There's a verse that refers to Inishowen (in Donegal - great festival there in March) - I've no idea why I don't sing it. It just doesn't stick in my head!
Regards
