Who believes that Robert Plant

Is THE BEST vocal in R&R?
Mmm, spent a lot of hours with Ian Gillan and Burton Cummings. And let's not forget the ladies. Lydia Pence, anyone?
What, no Freddie Mercury? Burton Cummings is another great voice, both with the Guess Who and his solo work. And while he was never a considered a vocalist first, Frampton's voice has really held up well over the years.
