Ian McMillan's guests celebrate hedges, with poetry from Alison Brackenbury and Testament, singing from Sam Lee, Michael Symmons Roberts explores a poem with a nightingale at its centre, and hedgelayer Paul Lamb records himself walking a hedgerow that's rich in wildlife.

This hedge-themed special features a haunted hedge from poet Alison Brackenbury, part of the anthology 'Lincolnshire Folk Tales Reimagined' (ed, Anna Milon and Rory Waterman). Alison's hedge started off life as a talking hedge in her non-fiction book 'Village' which is all about her childhood home in Lincolnshire (to be published online in July)

Testament, a world record-breaking beatboxer, rapper and poet, performs a poem called 'The Lig', based on his experiences observing three generations of farmer hedge-layers in Cumbria. Testament is a member of the Hot Poets Collective which explores climate change through spoken word poetry.

Sam Lee's most recent album is 'Songdreaming' - and he sings, not only in front of human audiences, but also with and alongside nightingales. Sam takes musicians and small groups of people into woodland for annual 'Singing With Nightingales' events - events which celebrate this vulnerable bird and our creative connection with it. Sam sings 'Bushes and Briars' on the show and explores the poetry of 19th century poet John Clare.

Poet and professor Michael Symmons Roberts chooses a 'neon line' for The Verb's ongoing series about stand-out lines in poems . His choice is from a poem that features a 'deconstructed hedge' and a singing blackbird. Michael listened carefully to the blackbirds in his garden whilst writing his new book 'Quartet for the End of Time: On Music, Grief and Birdsong', - inspired by his relationship with the music of the composer Olivier Messaien.

Ian also dips in and out of a very long hedge with the help of Paul Lamb, a hedge-layer who walks the Gower Peninsula to bring us hedge language. Paul's new memoir is called 'Of Thorn and Briar - A Year with the West Country Hedgelayer'
