They may have both been on 'Top of the Pops', but can Tony Blackburn and Alvin Stardust cut it as bargain antique spotters? The broadcaster who launched Radio 1 and the former chart topper, both try to make the biggest profit when items discovered at an antiques fair in Sussex are sold at auction in London. Tony is accompanied in his quest by fellow Radio 1 and then radio 2 presenter Colin Berry, while Alvin is accompanied by his wife Julie. Among the items Alvin loves is a 70s hi-fi pod, while Tony cannot resist a coat of arms bearing the Blackburn crest and a canon ball. During their day shopping, presenter Tim Wonnacott discusses Tony's interest in old gramophone players, and Alvin demonstrates the old acoustic guitar which his mother gave him and which he got many of the biggest names in music to sign, including all the Beatles and Buddy Holly. The guitar has recently been insured for a million pounds.
