Dark nights of the Soul, Brian Bilston, JH Prynne, Daljit Nagra, William Blake and Martha Sprackland

The comedy of corporate language, why a 16th century 'dark night of the soul' poem could help you through your own dark night, the experiments of J.H.Prynne, and the tenderness of boys' friendships - with Ian McMillan and guests Brian Bilston, Martha Sprackland, Daljit Nagra and Ira Lightman.

Brian Bilston's very funny books include 'You Took the Last Bus Home', and 'Alexa, what is there to know about love'? He reads from his new guide to reading and writing poetry: 'How to Lay an Egg with a Horse Inside'.

Martha Sprackland is a poet, essayist and poetry editor as well as a translator. She explores a poem called 'Dark Night' by the 16th century Spanish mystic St John of the Cross. It comes from her new book of translations, also called 'Dark Night'.

Daljit Nagra, poet, professor of poetry and radio presenter for BBC Radio 4 Extra reads from his new collection 'Yiewsley' (the 'Venice of West London' ) and illuminates this week's 'Neon Line' - a remarkable line in a remarkable poem.

Ira Lightman is a Verb regular, a poet and an artist. He dives into the words and ideas of J.H. Prynne, one of our most celebrated experimental poets who died in April.
