Jimmy Fallon is superb at doing musical piss takes, and as a Halloween suggestion from an audience member, he performs 'Trick or Treat' as Bob Dylan.
He sounds better than Dylan nowadays, and in fact, l have just had a brainwave while typing this.
What he should do (or someone else with the same skills) is re-record Dylan's last few albums, but using Dylan's vocal stylings from the late 1960's or early 1970's.
I'd buy them, as some of the songs are still really good, but it's the vocals that let them down. Not a new complaint as far as Dylan goes, but the voice now is so far removed from his earlier work, that it might as well be a different person.
Here's a repeat post of Fallon performing as Jim Morrison, doing 'Reading Rainbows'. It's better than The Doors themselves (not really).
