Gareth Malone and Alistair McGowan

Richard is at Buckingham Palace, for all the build-up to the royal wedding.

Everyone's favourite singing teacher Gareth Malone of The Choir fame comes along to talk about his new book Music for the People.

Alistair McGowan has left impressionism behind - he's the new villain in CBBC drama Leonardo - but still finds time to give us a bit of Becks and Tony Blair.
