Claudia Winkleman, Mika and Jon Batiste switch trains for planes as they bring their piano to Heathrow Airport's Terminal 5. It's the last stop on their quest to find the UK's best amateur pianists, and they have just one more place to fill at their final concert. There's an international flavour to the music as Jon and Mika are transported to rush hour in Hong Kong and the beaches of Brazil. Among the other pianists flying in to perform at Heathrow are a talented pilot, a romantic charity worker and a teacher with a medal from the Queen. Who will grab the last spot on the big stage?
