Took me 5 mins to figure out...will sound just like the CD...

-Put capo on 3rd fret

-Then play chord progression G, D, Em, and C (small chords, not bar chords).....however.....

-...during all four chords, be sure your pinky and ring fingers are continually pressing 
down strings 1 and 2 (the thinnest strings) side-by-side on fret 6.

Peace
