the whole song from what i can tell uses the chords G and C.  Someone else can improve 
this tab, but this is an extremely basic version that can be used as a great start.

G
Most people try to aim to please
D
but a lot of them are kind of weak in the knees
G
learnin' late about the birds and the bees
D
fallin' in love and want to be set free.

Playin' ball at the age of thirteen
everybody's growin up with a dream
I never noticed what could happen to me
time flies when you're walkin' the street

One minute got you holdin' an ace
the next minute got you fall on your face
a mean city is a nasty place
only a rat can win a rat race

Peace to the people who be fallin away
(please god) make it home today.
And peace to the people who be tryin to find
some kind of life

Sometimes I feel like I can do anything yeah
sometimes I'm so alive
Sometims I feel like I can zoom across the sky
Sometimes I'm so alive

Sound body and sound of mind
Sound of the rhythm
Sound of the rhyme
Somebody marchin all of time
Biggest mistakes are the humanest kind

Judge not lest you be judged
the court room or the billy club
blood bubblin thicker than mud
heart beats rub a dub dub

show love and love who you know
family wherever you go
tokyo to acopulco
bravissimo magnifico....

you can play a pretty mean version of this song with just these chords, but i hope 
can improve on it, so i can use their version to kick some serious guitarass.  enjoy
