No, I believe both Mick and Caoimhín are from Yorkshire, ... sorry!! Dublin
Thanks so much for that info. I've been playing his album with Mick O'Brien, "Kitty Lie Over." over and over and over. One or the both are from Co. Limerick, right?
"Caoimhin's 5-string viola was custom-made by a guy in Oregon whose name, I'm sorry to say, I don't recall. The extra string is on the lower side, so its "standard" tuning (low to high) is FCGDA." Paul
