You may recognize this song from a few Land Rover commercials.
Here's the bass part.

The Guitar does this same pattern twice, then enters the bass, and the rest of the band.

A-3--3------------------------3-1-3------|
E----------------------------------------|

D-----------------------|    X1
A-5-5-5-5-5-5-5-5-3-----|

G----------------------------------------|
D------1-3--3-1-5--5-1-3--3-1------------|     X4

Just repeat like that. Only those two patterns. Its a fun easy song to play, hope you enjoyed.
