Very sad to hear this. I used to see Frank a lot, and enjoyed his company many times in the 1970s when he was a regular floor-singer at Aberdeen Folk Club. He was the person who first introduced me to the delights of "Scotland The What", at his flat one night in Ferryhill, I think with another Aberdeen singer Alan Carr. I hadn't seen him in a long time, since he moved north, but had corresponded with him in a few threads here in the past. I hadn't known he was ill. Condolences to his friends and family - may he rest in peace.
