Jane McDonald, Rosemary Shrager, Louie Spence

Singer and presenter Jane McDonald, chef Rosemary Shrager and choreographer Louie Spence take part in the quiz show in which contestants answer questions to win turns on an arcade-style machine. Dropping tokens down a choice of four chutes, they hope to knock piles of them off a moving shelf - and the more they collect, the better their chances of collecting the £20,000 prize for their selected charity.
