Rude Kids is a punk rock band from Hagsätra. Their first single "Raggare is a Bunch of Motherfuckers", that they recorded themselves, was released by Polydor in 1978. Rude Kids was the first Swedish punk band to release a record through a major record label. The single sold between 5000 and 6000 copies (compared to 600-700 copies for an average Sham 69 single). Tony Parsons named it "single of the year". Polydor also released the single "Stranglers" and the LP Safe Society. Their records got good reviews in the press.

Rude Kids played in London a few times. Once they opened up for Madness (only realising at the gig that it was Madness, not Doctors of Madness) and were attacked by skinheads in the audience. After they fled the stage the audience smashed up all the gear without realising they smashed up Madness' gear.
