In 1972, McCullough passed an audition for Paul McCartney's new band, Wings, joining the bare-bones lineup of Denny Seiwell and Denny Laine (who were already aboard for the album Wild Life) in the first fully functional incarnation of the group. A hand injury in the early '80s left him sidelined for an extended period, and it wasn't until 1988 that McCullough re-emerged fully, leading his own band in Ireland. For the next decade, he confined his work exclusively to Ireland, but in the late '90s he cut a series of sessions for an album in Poland and toured the country. More recently, he has turned to songwriting and generated "Failed Christian," which was later recorded by Nick Lowe.
