Stephen E Diggle (born 7 May 1955)[1][2] is an English musician best known as a guitarist and later lead vocalist in the punk band Buzzcocks.

Diggle was born on 7 May 1955 at Saint Mary's Hospital in Manchester,[3][4] and grew up in the Bradford[4] and Rusholme areas of the city, where he was a mod.

Their manager Malcolm McLaren introduced him to guitarist Pete Shelley and vocalist Howard Devoto, who were looking for a bassist for their band, Buzzcocks.

Howard Devoto left Buzzcocks shortly after the EP was released, which prompted the band to reshuffle – Pete Shelley becoming lead vocalist as well as guitarist and Diggle switching from bass to guitar.

(co-written with Shelley, Garvey and Maher), "Why She's A Girl From The Chainstore", "Running Free" and, perhaps his most famous, "Harmony in My Head", a Top 40 hit in 1979.
