He's a character DC, and nae mistake.
Good pal of mine, though I've seen less and less of him last few years living oop North.
How did you have the dubious privilege of making his acquaintance?
Got to know Billy a wee bit through the aforementioned bro-in-law, and hung with him at a few social functions (as well as enjoying a hungover breakfast at his house after a wedding in Dumbarton many, many moons ago but that's a long story) and he's a genuine toff of a guy.
Sad to hear of his health trevails, hope he can get the better of it and have some sort of decent quality of life in his twilight years.
