when i was searching for bass tabs on this song, i mostly found this:
G|---------------------------------|
D|---------------------------------|
A|-3-3-3-3-------------------------|
E|---------3-3-3-3-5-5-5-5-1-1-1-1-|
but i didnt think that the G sounded very good, so i started playing around a little and
that

G|---------------------------------|
D|---------------------------------|
A|-3-3-3-3-2-2-2-2-----------------|
E|-----------------5-5-5-5-1-1-1-1-|
sounds much better. i find it difficult to express the rythm but you should be able to
it out easy enough, and because its such a simple line you can play around with it. when
listen to the song you find that in some places they play the F note higher, so instead
the first fret on the E string you can play the third fret on the D string
