Because when you say that his songs are cool but that “Dylan can’t sing”, the standard highly original lame reply on these pages, then who do you think ought to sing Dylan’s songs and how: Michael Buble, Liza Minelli, George Strait?
I purposely avoided hearing the Rolling Stones version of “Like a Rolling Stone”, believing that they or anyone can’t possibly add anything to it (some standards ought to remain untouchable), until I heard it on Youtube just yesterday. I had been correct, nothing was added in any way. You might have even thought that Al Kooper himself played the organ on the RS recording.
The only other singer I ever cared to hear sing Dylan’s songs is Joan Baez.
How Al Kooper, who thought he was going to play lead guitar when he walked into the studio, came to play the organ on that track is a GREAT story in itself. That it is an iconic organ is just icing on the cake...so to speak.
