'I've only ever heard the "folksinger's N" on recordings by Cork balladeer Jimmy Crowley, and assumed it was a regional Cork thing. Is Tim Dennehy from Cork?'

Tim is originally from Kerry, Cahirciveen but landed in the same place as myself, and Jim Carroll for that matter.

I don't think it's a Cork thing, I have heard other people describe it as 'a Northern thing' because they heard Len Graham use it extensively. Christy Moore is no stranger to it either. Or you'll find it in Joe Corcoran's 'Ronks of Bawn' for that matter.
