The Theme is the last chorus of "Hey Beautiful" by The Solids, just a little 
"bababahabah..." as lyrics. Sounds good, if you play the first two chords as 
powerchords and move your indexfinger back one fret after a few strums, so you get 
a powerchord with a maj7 in it.

The Chords are:

C - F - C - Am - G - Em - F - G - Em - G - G
        "babahbahba..."
