The connection of punk to reggae, was two-fold. There was a rasta DJ working the punk mecca - The Roxy Club! He played oldies, roots and dubs. His name was Don Letts and he appeared on the Cover of a Clash album - Black market clash. It's a famous picture of a lone rasta facing off a massed police line. The other connection was Daddy Kool's record emporium situated in the shadow of the Vortex Club. The Clash and other punks would visit and hangout to listen to the latest recordings from Jamaica.
The Clash would make reggae apart of their sound with songs like: Police & Thieves, Lover's rock, Wrong emboyo (ska), Bank robber and others. Other artists followed suit there was Watching The Detectives by Elvis Costello. Off Shore Banking Business By The Members. Jah war by the Ruts. Saturday Night Beneath the Plastic Palm Trees by Leyton Buzzards. What A Waste by Ian Dury and the Blockheads. Roxanne and Walking on the moon By The Police and a whole host of others.
