When the acclaimed guitarist Dennis Cahill passed away last June from complications after a long illness, he was with people he loved – his wife Mary, and his friend the musician Jimmy Keane.

In his last moments, as Mary kissed her husband goodbye, a piece of his music – ‘The Lament for Limerick’ – was played. Recorded in one instinctive inspirational take, it seemed to encapsulate so much of Cahill’s musical life – and its rich sonorities seemed to conjure another presence into the room: that of Cahill’s dear friend and longtime collaborator, Martin Hayes, who also played on the track.
