It seems like an age since we've seen Derek and Dervla of Crystal Swing on our television screens, so we were only too delighted to discover that their pair (and their mammy, of course) will be joining Brendan in the studio this evening. As if that wasn't enough, former Coronation Street star and I'm A Celeb diva Helen Flanagan is on the sofa and Katherine Lynch will be stopping by for a bit of a chat. Plus, Michelin-starred chef and Great British Menu title-holder Richard Corrigan is in the house.
