Laughing with Dylan on his birthday

I just took a daily walk up and down to the end of the street, laughing to myself while some of the funniest songs by BOB DYLAN played on my iPod.
I am listening to "THE BOOTLEG SERIES VOL. 6, BOB DYLAN LIVE 1964: CONCERT AT PHILHARMONIC HALL" on the occasion of the legendary singer/songwriter's 70th birthday.
It's hard not to laugh during "Talkin' John Birch Paranoid Blues" -- even the Philharmonic Hall crowd can't help roaring with laughter -- and Dylan himself chuckles at various points of the landmark concert.
He had said in various interviews that he was never intended to be taken too seriously -- as seriously as some people have taken him -- and at this gig, Dylan shows and shares his humorous side.
