The Edinburgh Festivals are 70 years old this year and The Verb is joining the celebrations from The BBC's Blue Tent. Ian's festival guests include the best selling Irish writer Colm Tóibín. Colm is the author of the novels 'The Master' and Brooklyn'. His latest book 'The House of Names', is a retelling of Greek tragedy, where he turns his attention to the gaps in the myths, imagining what might have happened to Agamemnon's son Orestes. Stand up Aditi Mittal has previously been heard in her Radio 4 series 'A Beginner's Guide to India'. For The Verb she explains the dangers lurking behind innocuous English phrases like 'Nice to meet you...' And we also feature a performance by the winner of the BBC Poetry Slam.
