Need a hand pretty bad

[Xiablo]

Hey guys,
I really need a hand on learning this groove, even if its not the full song, just the beginning and I can improv the rest. Its Victor Wooten, Beauford, bela, and jeff coffin in the song zenergy. The guys in the band I'm in had learned their parts to it and want me to learn the bass line so we can play it at an upcoming show....the problem is I'm pressed for time (gig date coming soon and VERY busy) here and having trouble getting it down.

Been searching for it and i've determined that its in the key of G but starting at D and sorta going backwords. Any help is REALLY appreciated. Heres the link to the song for those of you who dont have it:

Thanks for any help

I can play this song, I just got Vic and Carter's DVD and watched that to figure out, he plays the entire song pretty much in full view. It's really banjo-bass stuff.
