Strummer’s band, the Clash, were British punk’s militant wing. Jones invited him to join an early version of the group; their role as songwriting parters became central to it. Lydon’s Sex Pistols opened for Strummer’s former band: the Clash later reciprocated. Both Scorsese and Jarmusch were big fans, Strummer appearing in films by both. He had previous form with McGowan, and became an irregular member of the Pogues in the singer’s absence. They and Costello all appeared in a sub-standard film. Cash didn’t record the song Strummer wrote for him, and didn’t recognise him the one time they met.
