Chris Martin took to the stage to sing a rendition of REM's classic hit 'Everybody Hurts' during Coldplay's slot at the Music Midtown festival in Atlanta on Friday night.
Before the performance, Martin says: "One of our favourite bands of all time, REM, for some crazy reason have finished - and it's sad. So with the most respect in the world… this is just to show how much they meant to us."
REM split after 31 years together, recording 15 studio albums as a group.
The band told their fans: "We walk away with a great sense of gratitude, of finality, and of astonishment at all we have accomplished. To anyone who ever felt touched by our music, our deepest thanks for listening."
REM's Michael Stipe and Coldplay's Chris Martin previously teamed up for a performance of Joseph Arthur's 'In The Sun' back in 2006. The show raised money for the victims of Hurricane Katrina.
