That is very sad indeed. The show was an institution, and compulsory viewing in our household. I attribute a great deal of my interest in outback touring and camping to watching "Ask the Leyland Brothers" as a youngster. They don't make them like that any more and it's a great pity. Down to earth, none of the commercial hype and Fox-style "speaking inside a tin can for effect" super-sound that is thrown at you daily now.
RIP old mate.
