Guth, the irish word for Voice, is a six-part series on TG4 that illustrates the impact the Irish diaspora had on popular music in the US and UK in the second half of the last century.
Focussing on Bing Crosby, John Lydon, Morrissey and Marr, Dusty Springfield, John Lennon, and the Gallagher Brothers, through a combination of interviews and archive footage both of their work and emigrant life, Guth crafts a story that is part social history, part music documentary.
The series begins with crooner Bing Crosby, who had Irish Catholic ancestry.

Paul Gallagher, Liam and Noels older brother, features extensively in tonight's edition of Guth, a TG4 documentary series which explores the Irish roots and influence of some of the world's top musicians. The contributors to the show said the Irish roots of Oasis' five original members was integral to their success. The Gallagher brothers, whose mother Peggy hails from Charlestown, Co Mayo, and father Tommy, from Duleek, Co Meath, had "music running through their family", according to the programme. Paul said: "My mother reckons the music comes from our granny. She was apparently a great whistler and our father played the accordion and the guitar. There was always music in our family." The oldest Gallagher brother also spoke of the brothers' tough upbringing in Manchester, recalling how their mother used to make all their clothes. He said: "We knew we were different when we came back to school and all the other kids would have pristine jumpers from the stores and we'd be in our knitted jumpers."
