UPDATE:

When Kevin Barnes plays this, he actually uses a guitar that is tuned down 
a whole step, that is, two half-steps. Then the song is in Dm(relative to tuning):

   Dm                              F/C

Obviously this pattern has variations over the length of the song, and the
notes that are sometimes substituted are written in brackets.
