This is just the intro chords, I saw it wrong and dumbed down all over the place after one of my students
asked about it. Listen to the persistent high G note in all but the first chord and you'll get it, and check
out the cool Bb6 chord; the song's actually easier when played the correct way than some of the barre chord
stuff I've seen.
