Afternoon word game with the added bonus (if we remember correctly) of sometimes not having any adverts midway through the show, a bit like This Is Your Life (when it was on ITV, that's not something to be too impressed by on the BBC, is it?).
Based on the American show that's a bit like The Pyramid Game (indeed, the French show Pyramide probably has more to do with Password than it has to do with The Pyramid Game), two teams consisting of celebrity and real-life person compete in guessing passwords. If anything, though, 'Password' was even more like Three Little Words, which definitely did involve one-word clues.
One person gives a one word clue and their partner has to try and guess from that what the password is. If they don't then their opponents get a go but for less points. Keep going back and forth until someone gets it; keep going to a certain amount of points are reached then something good is bound to happen.
Based on a classic US Mark Goodson-Bill Todman game show.
Channel 4 version composed by Mr Lovejoy himself, Denis King. A clip can be found on the relevant page of TV Ark.
