Theme Songs - Ghostbusters Bass

this is pretty easy if you get the timing right, it sounds more
effective if you use you fingers rather than a pick/plectrum
the tune starts off with a guitar with the bass fill behind it, 

G|---3---12---11---10----11---19---15-|
D|------------------------------------|
A|------------------------------------|
E|------------------------------------|

then comes a drum roll and then the bass kicks in like so:
G|----------------------------|
D|----------------------------|
A|--------12----------12-12---|
E|-7-7-xxx--12--7-7xxx-----12-|

thats it, NOW IVE CORRECTED IT IT SHOULD BE 100% CORRECT.
