Her songs have been covered by the Wolf Tones, the Clancy Brothers, the Dubliners, even The Pogues... Delia Murphy, the folksinger known affectionately as 'Murphs', almost single-handedly prompted the Irish Folk Revival and captured in song an expression of emerging Irish nationhood.

In this programme for Newstalk 106, Sean Street, whose Irish mother loved the music of Delia Murphy, embarks on a personal journey and presents a profile of one of Ireland's most important singers:

"I grew up haunted by the sound of this slightly cracked, off-kilter voice, coming, it seemed to me, from another age, and from another world to my Portsmouth naval upbringing. Long after my mother's death - and Delia's - the music continues to haunt."

With contributions from Murphy's grandchildren, Ronan and Garvan Browne and Carol Kiernan, her niece Carmen, her nephew Leo and her biographer Aidan O'Hara.
