When the credits roll on The Hobbit: The Battle of the Five Armies next month, Peter Jackson's wonderful 15-year journey through Middle Earth will be complete. It will be a bittersweet moment, and it looks like Jackson's queued up the right music to send off the two trilogies. Billy Boyd — who played smooth-singing Pippin in the original trilogy — will lend his musical talents to the credits sequence, and you can hear the final song right now. Warner Bros. has released the music video for the song, fittingly-titled "The Final Goodbye," and it's a stirring trip down memory lane for fans of the films. Give it a watch above, and try to hold back the tears.
