A great song that I have performed with my band many times and I use these chords.

Capo 4

Strumming pattern for most of the song is DUUDUU

Chords Used (frets relative to capo)
C Em D Am G

E-x--0--x--x--3-|
A-3--2--5--0--2-|
G-2--2--4--2--0-|
D-0--0--0--2--0-|
B-1--0--3--1--0-|
e-0--0--0--0--3-|

(the D is a C chord moved up 2 frets)

Optional Intro (Not in Milo Greenes version but I add one)
C Em D C D (strum once then pause)
If you want to add a bit of interest to the chord progression I do the following:
For the first C flick on and off the B string every down strum after the first, Em same
with the flick off/on on the A string then with both the D and the second C use your
pinky on the high E string on the 5th fret for the D and the 3rd fret for the C with a
flick on and off.

and a changed melody sung on top and then Ooh's from this backing singer.
