WATCH: Coldplay's Chris Martin covers Wham!.

Chris Martin covered Wham! in a George Michael tribute this week. The Coldplay front-man was donating his time at a London homelessness charity called Crisis. This was a pretty low-key event in fact you can hear someone playing table tennis in the background. The other singer is pretty good but its hard to compete with a rock-star. Watch below.
