I'm going purely from memory,which is dangerous in my case (my fingers remember better than my brain, but I dont have my guitar with me right now) - I think I chord the first two lines of the chorus differently -

D   D   C   D
G   G   Bb A (followed by the run discussed by WesleyS but make sure the f is F natural (3rd fret 4th string) and not F sharp)

and the one beat C chord in the final lines can be replaced by a 0-3 run on the 5th string
