Rockers Coldplay have offered fans the chance to see their show for free - if they agree to volunteer for charity.
The Yellow hitmakers are touring the world until November (12), and they are giving away free entry to their U.S. concerts for their most generous fans.
The band has teamed up with Oxfam for its Grow Campaign, to stamp out hunger in underdeveloped countries, and to boost awareness of the cause they are asking their followers to give up a few hours of their time to promote the charity at their gigs.
As a result, the volunteers will get to see Coldplay's show for free.
