I didn't like how the others I've found sounded, so here is my version of the background 
the song.

Listen to the song (I'm sorry that I can't tab this out, but I am still learning notation..)

Chord #1: Em7

e|--3------------------------------------------------------------------------|
B|--3------------------------------------------------------------------------|
G|---------------------------------------------------------------------------|
D|-2-------------------------------------------------------------------------|
A|-2-------------------------------------------------------------------------|
E|---------------------------------------------------------------------------|

Chord #2: Some other version of E, I'll call Em9 just to give a name.

e|-2-------------------------------------------------------------------------|
B|-2-------------------------------------------------------------------------|
G|---------------------------------------------------------------------------|
D|-2-------------------------------------------------------------------------|
A|---------------------------------------------------------------------------|
E|---------------------------------------------------------------------------|

If you listen to the song, there is a combination of downstrokes and upstrokes.  It will 
most easy to learn the progression by listening to the song.

Chords will be in parenthesis, like (Em7)

Lyrics:
(Em7)      (Em9)                     (Em7)     (Em9)
My friends feel it's their appointed duty
(Em7)                   (Em9)                     (Em7)     (Em9)
They keep trying to tell me all you want to do is use me
But my answer yeah to all that use me stuff
