To follow on from Bronski Beats Jimmy Somerville joining in with a busker, here's some more pop stars being cool. First off, Marc Almond singing along to a video he was shown of floppy disc drives playing Soft Cell's 'Tainted Love.'
Plus Donovan, joining in with a busker in Glasgow, and performing 'Sunshine Superman'. More from the Donovan busk can be found here.
If only all pop stars were like this.
