This is before the novel peace prize concert. It was the inspiration for them to do this song together. So, This video was posted after the concert because it became so popular they put this up on RU-vid due to how good it turned out in the end. The date something is posted is always the same day it was filmed.
Really not as bad of a performance as some say in my opinion, just bad choice of microphones and not having the guitar plugged to an amp can affect the sound quite a bit.
