U2 are urging their fans to don face masks at their upcoming shows - to highlight the struggle of a political prisoner in Burma.
The Irish rockers are embarking on a mammoth stadium tour, which kicked off in Barcalona, Spain, on Tuesday night (30Jun09).
And the band are hoping to get gig-goers to show their support for the leader of the National League for Democracy in Burma, Aung San Suu Kyi, who has spent 13 years under house arrest.
The group want their fans to download her face from their official website - and wear it during their track Walk On.
Frontman Bono is a longtime social and political activist.
