so some would say Dylan can't sing...it's what they do with the music. they never pretend to be Sinatra...who did his thing but did not have a "great " voice. You want great voices, try the opera.
And what is with this age thing? there were no complaints about sinatra, BB King, etc. You guys are missing the fun.
Sinatra maintained his voice and phrasing up until the last three years of his life. The same cannot be said of Mick and the boys.
