This week, Shaun and Tim ranked their Top Ten side-long rock epics. Topics covered include: what constitutes a side-long track, how many different ways there are of structuring such a track, what differentiates normal art from working-class art, how many apotheoses you need in a side-long piece, and why all British side-longs seem to concern industrial development. Also, what’s the connection betwen Rick Wakeman and Paddington Bear? What does the Al-Hambra building have to do with the band Renaissance? What happened when Shaun’s art tutor met Vangelis? What’s the connection between Rush and Tom Jones? And most important of all, who will be number one?
