This is a real easy song, but a fun one.

The premise for the whole song is this riff:
        Am x4           Dm x4
e--------------------------------------------------------------------------|
B--------------------------------------------------------------------------|
G--------------------------------------------------------------------------|
D--------------------------3-5-3-------------------------------------------|
A----------3-5-3------5-5-5------------------------------------------------|
E-----5-5-5----------------------------------------------------------------|

Then the chorus just goes C5-A5-D5

Then it returns to the main riff.

That's pretty much it. Not much going on so its a real fun song just to jam to. Have fun!
