i think he plays it in the key of D with the capo on the 1st fret and the G chord is actually Gsus4.so the verse is D G D A x2 and the chorus is G A D - G A D - G A D D/C# Bm -G A D.
i think the bridge is:
C G D i know you'll be a shining star C G D in someone else's sky C G D i remember all the times A i held on to you and kept the dream alive
