"Doing It To Death, Pt. 1" (The JB's)

From 1971 to 1976, James Brown had his own label, People Records, which he used as a venue to record members of his roadshow, the James Brown Revue.  The People roster included artists like Lyn Collins, Bobby Byrd, Marva Whitney, as well as The JB's—the Fred Wesley-led backing band for Brown himself and all of his acts.
Thing is, it's often hard to distinguish a "James Brown" record from a record credited to these other artists during that period.  Most of the time, Brown can be heard shouting directions to the band, yelling his signature uhn!, or even singing on songs that bear other artists' names.  
Such is the case on the 1973 single "Doing It To Death" by The JB's.  It's Brown's voice you mainly hear throughout, singing the refrain (Gonna have a funky good time) and giving the band its cues, including telling them to modulate from the key of F down to the key of D in the middle of the song.  (I've always assumed it's because Brown was having to strain a bit to hit the top note on We gotta take you hiiiiiigher.  Listen to his rasp on the second refrain.)  But, really, who else but Brown could get away with yelling out a key change in the middle of a song and not only make it work, but also turn it into a #1 hit?
Unlike some of his other songs from the early 70s, there is no political statement or deeper sentiment here.  This one's all about laying down a funky, sweaty groove.
Oh, and if you thought a trombone couldn't get funky, take a listen to Fred Wesley's fluid, minute-long solo in the middle of the song.
