Can you remember who was awarded the BBC Sports Personality of the Year trophy for 2011, just a few weeks ago? Russell Davies puts the contestants on the spot in Brain of Britain, and you can hear how they get on in this week's programme.
The time-honoured general knowledge quiz reaches the semi-final stage this week, with four competitors who have come unscathed through the heats continuing their progress towards the title Brain of Britain 2012.
The first batch of semi-finalists are from County Fermanagh, Merseyside, London and Sussex.
