There are heaps of versions out there on the internet involving bar chords. I can play
bar chords but i know many guitar beginner's can't yet. Clarification: I do not like this
song, but (argue with me all you want) it is a really fun song to play in jam sessions 
with your friends. So enjoy :)

I will give you both the bar chords (if you do not have a capo) and the version with capo.

No capo : Keep playing chords B, Abm, E and F# throughout the whole song. The chords
look like this:

B
E- - x - - -
B- - - - x -
G- - - - x -
D- - - - x -
A- - x - - -
E- - x - - -

as you can see, you bar the 2nd fret and play an A chord.

Abm
E- - - x - - -
B- - - x - - -
G- - - x - - -
D- - - - - x -
A- - - - - x -
E- - - x - - -
so here you bar the 4th fret and play an Em chord

E
E- - - -
B- - - -
Gx - - -
D- x - -
A- x - -
E- - - -
this is not a bar chord

F#
E- x - - -
B- x - - -
G- - x - -
D- - - x -
A- - - x -
E- x - - -

so this is where you bar the 2nd fret and play an E chord

The chords go in this order
B
Seven a.m., waking up in the morning
Abm
Gotta be fresh, gotta go downstairs
E
Gotta have my bowl, gotta have cereal
F#
Seein' everything, the time is goin'
B
Tickin' on and on, everybody's rushin'
Abm
Gotta get down to the bus stop
E                   F#
Gotta catch my bus, I see my friends (My friends)

and continues like that throughout the song

If you are using a capo, put it on the fourth fret and play chords
(relative to capo)
G, Em, C and D.
