Hi, I'm the same guest as before (I didn't leave my name then by error). I don't think that's Joe Brown (he didn't have such a white hair a few years ago, less back in 1987), and he cannot be George's father, since he died in 1978. I don't know whether this man is a musician or not, but obviously he's no violinist, unless he's playing the fool (by bowing in that way you cannot produce anything but a scratching sound).
