It's the worst sounding thing you've ever heard
And I imagine I'm one of the bigger Dylan fans that peruse these boards.
He'll sing a Girl/N Country and Johanna, but you won't recognize it.
I'll say this, though, in 2006 at Jazz Fest, he played Don't Think Twice with just his voice and an acoustic guitar. It is something I'll always remember.
but it'll be the worst voice you've ever seen live-literally.
