A troupe of roving British buskers have shot to fame on Facebook after a radical protest song struck a chord with voters preparing to elect the country's next government on 7 May.

The group Phat Bollard makes a living travelling around the UK playing to passersby in city centres. A mobile phone recording of their song "Millionaires", which criticises big business and peoples' attitudes towards the homeless, has been viewed nearly three million times on Facebook.

They say they're not supporting any political party - lead singer Patrick Shevlin says he's not even going to vote. So who are they, and why has the song been so popular?
