Coldplay joined by Michael Stipe

Coldplay were joined by Michael Stipe at their show in Atlanta last night (September 28).

The REM frontman duetted with Chris Martin onstage at the Philips Arena for a rendition of the track ‘Nightswimming’.

Introducing Stipe, Martin told the crowd that the last time Coldplay played Atlanta they were joined by Elton John on piano and they wanted to do something to top that.

One fan told NME.COM: “Stipe got a huge standing ovation, and they couldn’t start the song for a minute or so because it was so loud. It was unbelievable.”

Earlier in the show, Martin worked in references to Outkast and REM during ‘Politik’ and played a few bars of REM’s ‘Perfect Circle’ in between songs.

Before launching into the band’s untitled Johnny Cash tribute song – which was merged with ‘Ring Of Fire’ - the Coldplay frontman said that was one of the great American singers, alongside Bob Dylan and Stipe.

Coldplay rounded off the night with ‘In My Place’ and ‘Fix You’.

The group’s US tour hits Virginia Beach’s Verizon Wireless Amphitheater tonight (September 29).
