Haim cover Beyonce's 'XO' at the BBC Live Lounge Wed-26-Feb-14 10:54 The BBC Live Lounge pulls in some of the world's biggest music stars and gets them to cover other big music stuff's massive tracks. So it's just all round awesome in one room. In the latest one, US sister trio HAIM (who were just here the other week for Laneway Fest and were AMAZING... oh and they're fun to hang with too!) cover Beyonce's massive 'XO'. It's different... but good different. Share this Become a fan of The Edge on Facebook and on Twitter .
