Johnson developed his own image, coupling jerky movements on stage (his so-called "duck walk") with a choppy guitar style, occasionally raising his guitar to his shoulder like a gun, and a novel dress sense (he favoured a black suit and a pudding bowl haircut). He achieved his playing style by not using a pick but instead relying on fingerstyle. This enabled him to play rhythm guitar and riffs or solos at the same time creating a highly percussive guitar sound. It evolved from a failed attempt to copy Mick Green of Johnny Kidd and the Pirates, a guitarist whom Johnson greatly admired. His Bo Diddley-influenced style formed the essential driving force behind Dr. Feelgood during their initial years, including the band's first four albums, "Down by the Jetty", "Malpractice", "Stupidity" and "Sneakin' Suspicion", all released between 1975 and 1977.
