The Clash frontman Joe Strummer was a big fan of football, having used the game as a way to bring the band together during rehearsals.According to a press statement, “During rehearsals at Vanilla Studios in Pimlico for the recording of London Calling in 1979; he and the rest of the Clash played lots of 5-a-side and used football as a means of bringing the band closer together, getting them tight and making them play together as one. Local kids would come and knock on the door and ask them to play.”The JSF FC ‘Strummer United’ campaign aims to promote equality, inclusivity, and diversity, while providing opportunities to young people.The Umbro x Joe Strummer Foundation shirt features an exclusive Strummer football motif, with the back of each shirt emblazoned with ‘STRUMMER 22’ player details.
