Felt compelled to share this tab with you after seeing the other basstab for this song 
that wasn't quite right.

Here's how to play the beginning of the song:

G|------------------|------------------|------------------|
D|------5-3-0-5-0-3-|------5-3-0-5-0-3-|------5-3-0-5-0-3-|
A|------------------|------------------|3-3-3-------------|
E|3-3-3-------------|3-3-3-------------|------------------|
------------------|
------5-3-0-5-0-3-|
------------------|
3-3-3-------------|

And here's when the singin comes in:

G|------------------|------------------|------------------|
D|------5-3-0-5-0-3-|------5-3-0-5-0-3-|------5-3-0-5-0-3-|
A|------------------|1-1-1-------------|3-3-3-------------|
E|3-3-3-------------|------------------|------------------|
------------------|
------5-3-0-5-0-3-|
------------------|
3-3-3-------------|

Listen to the song for the timing and all.
