Peter Bjorn And John - do-si-do, 2016

"Peter, Bjorn & John had a major hit in 2006 with their song 'Young Folks', a perky little indie-folk ditty that has since been used on tonnes of TV ads. The trio released three albums after they scored their biggest hit - the most recent being 2011's 'Gimme Some' - although none have replicated the success of the catchy whistle-led number."
