I think the following link contains the song that the OP is after. Someone has provided sample chords in C later on the page:
Listening to the song "in my head" for just a second or two, I'd be inclined to change the chords on the second line of the chorus to the following...
G/G/C/C7
...and I'm also inclined to add a couple of extra beats, starting with a C7, immediately before each bridge or chorus.
Hope that helps,
Paul.
