Rat Noir

I'm wondering if Cupla Fir is a mash up of Cula and Newfoundland Duo. I chatted with the dad (forget his name now) of Newfoundland Duo back in November. His son was taking a break from the cruises as he was newly loved up, so he was looking to throw something together with Brian from Cula. Cula was going to be changing as Tommy was going off with a harpist! Tangled web much?
