Mark Radcliffe and Stuart Maconie begin their weekly discussions about BBC Two's new six-part music series I'm In A Rock 'n' Roll Band!, which investigates what makes the "perfect" rock group. Starting today and over the next five weeks, Mark and Stuart review each episode of the series on their show, continuing the debate raised by that week's TV programme. Is a drum solo ever justified? Does every member of the band secretly want to be someone else? Was there such a thing as a "front man" before Mick Jagger? The TV series, narrated by Mark Radcliffe, delves into the world of rock 'n' roll bands, dissecting the roles of the individual members to look at what makes them tick. It then pieces the band back together, investigating the secrets of their success, culminating in a live studio show on June 5. In tonight's programme, Mark and Stuart feature clips from the TV programme and bring the debate to BBC Radio 2's listeners, encouraging them to take part in the online poll and vote for their ultimate rock 'n' roll musician. Alongside the content on BBC Two and Radio 2, fans will also have the opportunity to get involved with an online poll at bbc.co.uk.
