What, I think, gets very little credit is the quality of Roger's live backing vocals through the years. They (and perhaps to a lesser extent, Brian's) are a massive element of the Queen live sound.
Roger sings a huge amount throughout concerts and other than the '39 high note fails (which I find difficult to object to as I see the originals as very much point in time studio creations), I honestly can't think off-hand of many instances where his harmony work was anything less than exceptional.
Yes I agree...And he still has it...even lead vocal duties like on Under Pressure these days are a joy to listen to. Freddie wouldn't have managed to sing as well without his back up vocals. Brian's are the icing on the cake.
Legit think Rog's drumming has got better through the years. That's not to suggest he's not gotten slightly less agile or a little slower (only natural with age etc.). But he's just so crisp and tasteful.
Also, I live for that hi-hat opening with the snare. Not a sweeter sound in drumming in my opinion. I'm a drummer myself, got into the drums because of Rog, and opening the hi-hat with the snare is almost second-nature to me now just because I'm so conditioned by the sound of it. I'm still waiting for someone to recognise it when I play, but they never do. Always feel the Queen boys miss out in public as being considered in the top levels of their instruments, which is a shame.
