Queen on 'Whose Line Is It Anyway?'
This was on the American version of the show, and in a game called 'Greatest Hits'.
To be honest, Wayne Brady and Chip Eston made it sound anything like Queen. But the two of them sang to the beats of Bicycle Race, You're My Best Friend, and various others. I might add, the music was not the typical Queen thing either but - it was all worth a shot!
