Did you not like the Mike Yarwood impression? I have no idea if Heath ever said Silly Billy, it may even have been a sh.it impression of Denis Healy, all of Yarwood's skits tended to blend into each other. You don't see so many impressionists on TV these days although Steve Coogan and Rob Brydon are still knocking about. F.uck me, I just remembered Faith Brown! She was a feckin awful impressionist but she had massive tay tays. please log in to view this image
