Paul Gambaccini welcomes the last of this year's Counterpoint semi-finalists to the BBC Radio Theatre, for the contest that will decide which of them appears in the 2013 Final.

At stake is a real chance to lift the silver trophy as the 27th Counterpoint champion. This week's semi-finalists are from Cheltenham, Bury St Edmunds and Debden in Essex.

To make it through to the Final they'll have to draw on the widest possible musical knowledge, from Wagner and Beethoven to Stevie Wonder and Bruce Springsteen. As always there are plenty of musical extracts to identify, both familiar and surprising.
