Paterson Joseph bunked off school when he was thirteen and spent the next two years going to the local library instead, reading his way from Agatha Christie through to Alexander Pushkin. It was a good training for someone who's become one of our most versatile and successful actors. Paterson Joseph is well known from numerous Shakespeare productions at the RSC and the Royal Exchange Manchester, and from Casualty and Dr Who. He achieved notoriety as the grotesque boss Alan Johnson in Peep Show. Paterson Joseph has recently been touring America with a show that he's written himself, about one of his heroes - the black 18th-century London grocer and composer Ignatius Sancho.

He talks to Michael Berkeley about why Sancho has been unjustly neglected, and what he thinks about "colour-blind" casting.

Music choices include Tchaikovsky's Eugene Onegin, Louis Armstrong, Bach, Charlie Mingus, Billie Holliday - and Ignatius Sancho.
