Keith Richards by far.
He already looked like a cross between heroin chic and three days post-mortem back in the 1980's.
I heard Stairway one more time, last night 100.3 The Sound's My Turn listener guest DJ, they wrapped up the hour with it. I can do with hearing once a year at this point.
I respect Robert Plant's decision, it's not often you see an artist who has made it over 40 years without compromising artistic integrity. Hell, you rarely see a contract where the artist retains artistic control.
If he only wants to move forward in writing and performing, I have no beef with that.
I still appreciate it when one of my favorites is still willing to tour and play their hits, like Pink Floyd and the Stones. But Waters, Gilmore and Mick Jagger never had high registers in their voice, Plant did.
And I really don't think Robert Plant could sing Whole Lotta Love in the original key.
