Nice find. Roger really is an awesome singer. He's even better here: http://www.youtube.com/watch?v=uFVOGTo9c8k&feature=relmfu
As Grateful Fan said on another thread, what a group Queen were to have someone as good as Roger as only a back-up vocalist. He could easily have been the front man in a successful rock band (ignoring The Cross -- undermined by weak, weak songs). And he could easily be the lead vocalist on any new Brian/Roger collaboration without having to bring in others who don't have a feel for the songs (Paul Rodgers and Adam Lambert, Im looking at you!)
Really good stuff this.
I find it's interesting to hear another top guitarist playing a 'Queen' song, not something I hear too often. If you were going to give Beck and Taylor one Queen track to have fun on, what would you give them?
Radio Ga Ga strikes me as an obvious one ...
