Drum duo begins right at 13 minutes. Berry Oakley's bass solo follows, and if you listen closely at the 22 minute mark you'll hear someone (I'd guess Gregg) count in "One-Two-Three-Four!" before Dickey and Duane rip it up. Betts is up front for the first minute, then Duane just goes . . . goes somewhere cosmic.
