tuning for 'i think i'm going to hell'

[primushead]

Wow, that video helped so much.  I could finally see how Jim was playing the song and tuned accordingly...however, i'm not sure what key it is played in.  Anyone know?

Eisey tabbed it on the tabs page.  According to him the tuning is:

Bb F Bb F Bb D

But that's way too much trouble for me, so I usually put it into open D
