[3] Caitlín O'Riordan was born in Nigeria to Irish and Scottish parents, who moved to London when the Nigerian Civil War broke out in 1967.
[4] In 1982, she was invited by MacGowan to join his newly forming band Pogue Mahone as the bass guitarist.
She appeared on the group's first two albums, Red Roses for Me and Rum Sodomy & the Lash, the EP Poguetry in Motion, and several early singles, before leaving in 1986.
Besides playing bass, she provided vocals for "I'm a Man You Don't Meet Every Day" on Rum Sodomy & the Lash,[4] and for "Haunted" on the soundtrack to Alex Cox's film Sid and Nancy.
The Pogues' most commercially successful song, "Fairytale of New York" from If I Should Fall from Grace with God, was written as a duet for O'Riordan and MacGowan, but the band eventually recorded it with Kirsty MacColl singing the female part.
[5] O'Riordan became romantically involved with Elvis Costello in 1985, while he was producing the Pogues' album Rum Sodomy & the Lash; the relationship lasted 16 years.
She left the Radiators and was replaced in February 2006 by Jesse Booth, and went on to form a band of divorcées named PreNup with Hothouse Flowers guitarist Fiachna Ó Braonáin.
