Hey, I saw the chords for this song were incomplete, and I wanted to learn to play this
so I did it myself...the chords are 98% correct I'd say, towards the end I had a little
not the best at tabbing songs, but verse/chorus chords are perfect.  Enjoy.   -L. Martin

Bright Eyes - "A Celebration Upon Completion"    standard tuning
Intro is basis of the song's finger picking style....

C (x32010@1)C/B (x2555x@1)G6 (320000@1)C (x32010@1)(2x)

In between the chords  C and C/B, and C/B and G6, there is a  3-1-0/1  figure on the B
that you should note should you want to play the song like Conor does on the album.  I
have the time or knowledge on how to tab it, but I can definitely play it myself, sorry 
I can't help you there.  Use your pinky hit the B string, 3rd fret while playing C and
chords, andafter a while , it should come along.   Good Luck.  Great song, by the way.  thnx.
