Simon Mayo takes over Radio 2's Drivetime show today and presents a programme packed with entertainment, information, intelligent conversation and audience interaction. Matt Williams joins Simon with the sports news, while Rebecca Pike presents the Money feature. Drivetime will also be the home of Radio 2's Great British Songbook initiative - the network's celebration of the work of British songwriters by creating a collection of their finest songs - and from time to time Simon will be joined by top artists performing their own version of their favourite British song. First to perform live is Scottish songstress Amy Macdonald who features on today's show just after 6pm.
