Peter Bjorn and John are a Swedish indie pop/rock band formed in Stockholm in 1999, named after the first names of the band's members: Peter Morén (vocals, guitar, harmonica), Björn Yttling (bass, keyboards, vocals) and John Eriksson, known in his solo work as Hortlax Cobra (drums, percussion, vocals). Yttling also worked as producer for the band's first four albums.

Their 2006 single "Young Folks", which featured Victoria Bergsman, formerly of the Concretes, was a top 20 hit in the UK Singles Chart, and was featured in the football video game FIFA 08, the baseball video game MLB 2K13, the singing game Lips, as the school project in the film Bandslam, as part of the soundtrack of sitcom How I Met Your Mother, the opening track in the pilot episode of Gossip Girl, the theme tune to British Television adverts for Homebase store, and in the Air New Zealand "Safety Safari" surfing video. It was also named NME's second-best track of 2006, beaten by "Over and Over" by Hot Chip. In Australia, it was voted number 16 in the annual Triple J Hottest 100 for 2006. In recent years, Lars Skoglund of the band Laakso has filled in for Eriksson on drums and played bongos during some live shows since the latter developed tinnitus, and incurred a shoulder injury on the tour for 2011's Gimme Some.
