In the mid-1980s, “Clannad, a family output from Donegal … were best known for the startling ‘Theme From Harry’s Game,’ recorded almost entirely in the Irish language itself,” (FarOutMagazine). “Their horizons were widening, and they felt confident enough in their abilities to work with a singer of Bono’s calibre by the time they recorded ‘In a Lifetime’ (1986). They were a family unit, no hollow metaphor, but a signifier of their place as a family of artists … They were a lo-fi pastoral band from the north of Ireland who were determined to bring the mysteries of life into the forefront, by channelling the songs and tapestries of their forefathers.” By contrast, Bono (lead vocalist of the band U2) “came a world away from that, having grown up in Dublin on a diet of The Sex Pistols, The Clash and The Who.
Paul Hewson was nicknamed ‘Bono’ on account of his strong vocal prowess, and he was adept at trying out new styles of singing … ‘He just walked in the studio and improvised his vocal in two takes, making up a lot of lyrics on the spot,’ Clannad singer Maire Brennan remembered. ‘The whole thing took about 10 minutes. It was one of the most remarkable things I’ve ever seen in a studio,’ … Bono showed that he could work outside of the U2 bandwidth to create compelling vocal demonstrations. His voice melds nicely with Brennan’s, and the two vocals slide in and out of the work to create a more impressive vocal choreography,” In the video, “tellingly, the two vocalists have their backs turned against each other, guided by the power of their partner’s timbre.” Brennan’s death at age 73, after several years of fighting lung disease, was announced today (The Guardian).
After an initial intro of a cappella chant, “In a Lifetime” begins in earnest at the 0:22 point with a more structured intro. Brennan’s vocal is in A minor; Bono’s first feature shifts to D minor starting at the 1:00 mark. The two keys alternate from there.
