Tennis legend Onstage, Roger Federer performs with the band Coldplay

Roger Federer, a 20-time Grand Slam winner who announced his retirement from the tennis circuit last year, was recently seen at a Coldplay event as part of their “Music Of The Spheres World Tour” in Zurich. Even while performing live, the former world number one sang along to a Coldplay song.

The very popular English band Coldplay performed at the Letzigrund stadium in Zurich.

Chris Martin, the band’s main vocalist, tells the audience that he will be joined by none other than Roger Federer just as he is ready to begin another song on stage. The crowd then erupts in jubilant applause as Martin and the musicians join Federer in singing “Don’t Panic.”
