Readings from Trainspotting two

Trainspotting, with its eyebrow-raising content and black humour, took us on a journey through Edinburgh's dark underside.

Irvine Welsh enjoyed great success with the novel and its film adaptation - and his new novel Porno has been equally well-received by critics.

Welsh reads from and discusses his new work, which revisits the Trainspotting crew - in particular Sick Boy - ten years on. After a spell in London, he's penniless and back in Edinburgh with a drugs habit to support, a low-rent porno film to be made, and a girl to exploit.
