fwiw, I would have loved to have heard the GD play "Fever" (or one of his other classic covers), instead of any of the 3 big Bobby blues #'s (LRR, CCR, WB's).
No need to isolate Bobbys slide tracks, eh?

.
Bobby has a great sence of playing between the major CAGED inversions, often creating new chord forms by way of including open ringing strings and dissonent fingerings.
His string bending techniques and hammer-ons of partial chord forms alone are a large part of his contribution to the GD magic.
I'll have to check that GD Movie DVD for the separate mix's.
Yeah, It'd make a good study to decipher what Bobby is doing on say, the PITB space jam.
With that said, I mean, a guy could spend one weekend studying Bobby parts, and come away with alot of new rhythm guitar licks to use on the next weekends gig.
It's not like trying to learn a different instrument like Sax, Pedal Steel, or Banjo.
I saw the Bobby/Wasserman duo a coupla times, and I thought what Bobby played was great, although at times I thought... these guys are totaly out of sync.
Fever!!! [throw head back and stare into space].
