Yes, Shambles, generally, they do -- at least, they know his name. He's appeared several times as a guest on PBS TV specials, and, maybe even more significantly, on Sesame Street (which is iconic in American culture), so if people were of that age to be a fan of that show in the seventies (in their 30's or 40's, now), they probably at least know what he looks like and that he plays the banjo, even if they don't know all the details of his political work.

How big a cultural figure is he in Britian, generally?
