Former members of The Clash, guitarist Mick Jones and drummer Topper Headon, have recorded a new version of their 1978 song, 'Jail Guitar Doors', in aid of the campaign of the same name run by Billy Bragg to help rehabilitate prisoners through music. This was the first time the Clash pair had been in the studio together for 30 years.

In a statement, Headon said: "When I was in prison myself, many years ago, I was lucky enough to have access to a guitar, which belonged to the prison vicar. I know how much it helped me get through it".

The recording session was filmed for a documentary about the scheme, called Breaking Rocks. The film will premier at the Raindance film festival at Proud Galleries in London on 1 October, followed by live performances from Bragg, Jones, MC5's Wayne Kramer, Foo Fighters' Chris Shiflett and more.
