Fiddler on the Roof lyricist, how musicals have evolved since 'Fiddler', Olafur Eliasson

All day long I'd bidi-bidi-bum... Sheldon Harnick is 93 and won worldwide acclaim as the lyricist of the hugely successful Fiddler on the Roof. As a new production of Rothschild & Sons, one of his lesser-known musicals, opens in this country he talks about a lifetime of lyrics.

Britain's first professor of Musical Theatre, Professor Millie Taylor, and theatre critic David Benedict discuss the evolution of the musical since the premiere of Fiddler on the Roof in 1964.

The Danish Icelandic artist Olafur Eliasson is best known for his large-scale installation art using natural elemental materials, such as The Weather Project, a dazzling sun in Tate Modern's Turbine Hall. Nikki Bedi met him at his studio in Copenhagen to discuss his views on the cultural landscape of Denmark, artistic collaborations and breakdancing.
