I can see where you are coming from Mamyalynne but you are right, Anne Aston did not die young, she was 55 when Bob Monkhouse died and paid tribute to him in a newspaper article. But the contestants did say up,up,up. The only other one I remember where the contestants might call this (not the hostess) was Play your cards right - I think that's what it was called with Bruce Forsythe.
