An unlikely 'supergroup' was formed on Wednesday night when Coldplay, Bono, Brandon Flowers and Take That's Gary Barlow took to the stage at London's Shepherd's Bush Empire.
The gig was a post-Brit Awards event to benefit the War Child charity. During Coldplay's set, Chris Martin said to the crowd: "We've just got back from Japan, lost all the Brits, it's been a shit day frankly, but it's going to get better, please welcome Mr Gary Barlow!"
Coldplay then proceeded to serve as Barlow's backing band as he sang Back For Good.
"We stole this song from Steve Vai"
Just as fans were recovering from that knockout blow, on came Bono and Brandon Flowers to join Coldplay and Barlow for a one-night-only rendition of The Killers' All These Things I've Done.
Before starting the song, Flowers said: "We stole this song from Steve Vai, but don't tell anybody".
Could he have been making a not-so-subtle reference to Coldplay's ongoing dispute with Vai's former teacher Joe Satriani? Almost certainly and, in doing so, he also made it pretty clear which horse he's backing.
