Barbara,I looked "gink" up in the dictionary and the definition I found didn't make sense in the context of the song; Gink slang, a man, especially one thought of as foolish or contemptable.
A priest unshorn makes more sense to me...
Pete, I think of nor'wester as referring to wind, but I thought that in the song "Paddy West" the expression might be used metaphorically, perhaps referring to some good times they had? Or maybe that when the cold nor'wester were blowing the fellows were glad to be at Paddy's instead at sea?
