WOW! I have never seen this before! Muddy singing and walking down a railroad track, to a train station that is the stage! According to the host site the video is from the American Folk Festival in 1964! I am not sure why the audience starts laughing around the 2minute mark. They also talk during the song as well, which to my ears is disrepectful. Perhaps the kids didnt know who was playing, or understood just how important that man on the stage was. Those people didn't realize how lucky they were to see Muddy Waters in his prime. Very sad. However, Muddy keeps on going and looks cool doing it!
