Claudia Winkleman, Mika and Lang Lang return for a brand-new search to unearth more of the UK's most exciting amateur pianists, starting at Manchester Piccadilly station.

At Cardiff Central train station in Wales - 'the land of song' - the search for more amazing amateur pianists continues with triplets and a man on a bike singing about conkers.

At Edinburgh Waverley station, Claudia, Mika and Lang Lang are blown away by a boy in a bow tie and charmed by a piano-playing postie, and get caught up by an Argentine tango.

At London's Victoria Station, a romantic milkman plays his heart out. There's a soulful rugby player. And Lang Lang hails 'the new Bach'. But who's going to the final?

At Liverpool Lime Street, Claudia, Mike and Lang Lang hear the skills of a rapping call centre manager and the infamous Billy the Hat, and join with in a station sing-a-long.

With the final concert approaching, Mika, Lang Lang and Claudia make a surprise late change to the line-up as they get the chosen amateur pianists ready for the big stage.

It's the big night. At the final concert the pianists play live in front of a sold-out auditorium. Who'll be awarded the coveted performance of the night?
