Bono, The Edge collaborating on new musical

U2 star Bono and The Edge are to collaborate with 'Once' director John Carney on a new musical film.
'Sing Street' is based loosely on events from Carney's childhood, and will centre on a boy who uses music to help him cope with moving from a posh private school to the inner-city, reported Digital Spy.
Bono and The Edge are slated to contribute songs and other musical elements to 'Sing Street', The Weinstein Company announced.
Carney is writing the screenplay, in addition to serving as director.
U2 won a Golden Globe earlier in the year for writing the song 'Ordinary Love' for the Nelson Mandela biopic 'Mandela: Long Walk to Freedom'.

The Irish rock group have previously contributed music to the films 'Faraway', 'So Close!', 'Batman Forever' and 'The Million Dollar Hotel'.
U2 are also currently working on a new studio album, although a release date has not been set.
