Beginning in the late 1970s, he was lead singer and co-founder of the punk rock group The Radiators from Space,[1] receiving some critical acclaim but little widespread popularity or financial success.
Following a temporary breakup of the band in 1981, he lived in London for a while, meeting and befriending Shane MacGowan through time spent working together at a record shop.
Following the release of the Pogues' 1984 debut album Red Roses For Me, he was invited to join the band on a short-term basis as cover for banjo player Jem Finer's paternity leave.
He took over as guitarist following MacGowan's decision to concentrate on singing—thereby becoming a full-time member of the band in time for the recording of its second album, Rum, Sodomy and the Lash.
[6] Chevron was openly gay and penned the anti-homophobia song "Under Clery's Clock", which was first performed in 1987 when The Radiators reformed for one gig, an AIDS benefit in Dublin, and released as a single in 1989.
