I don't remember that line, but there was a Bold washing powder advert many years ago where a white coated washing machine engineer service type guy said to a young boy "That's progress Sam".
DVS is absolutely right. I don't know why I thought it was an advert. A small boy asked Bill Heslop for his autograph when he was running for some government post. After he gave it, the boy ran off shouting the line in question. Cheers DVS!
