Natasha Raskin Sharp presents a special show to celebrate the BBC's 100th birthday, with two teams of famous faces going head-to-head at an antiques fair in Newark. On the red team are broadcasting legends Tony Blackburn and Gyles Brandreth. Their opponents in blue are presenter and writer Josie d'Arby and broadcaster and drummer extraordinaire Owain Wyn Evans. Experts Thomas Forrester and Chuko Ojiri are on hand to help them choose three items to take to auction. Which top TV team will bring home the victory? Natasha also dips into the BBC archive as she takes a journey through 100 years of memorable moments, starting from its radio launch way back in 1922!
