Simple:
verse is just G and C like this:
G        C             G       C                 G            C 
   There isn't much to gain by living it all the same way the years...

The same rhythm all the way until the chorus:

G        C             G               F
She came up to me said    wanna know a mystery
G                             C                   G             F
theres a whole wide world for you to see your the player in the game

The G C G F are also used under the instrumental parts

I use Cadd9 (x32033) to simplify it even more.
