Swedish House Mafia say goodbye with YouTube release of final song
Swedish House Mafia will release a farewell track tonight.
The 'Don't You Worry Child' hitmakers - consisting of Axwell, Steve Angello and Sebastian Ingrosso - disbanded in March after playing at the Ultra House Festival in Miami, but now they are set to go out in style with a revamped version of their very first single, 'Leave the World Behind'.
