I saw this when it was first broadcast and thought even then that it was an inspired mismatch of musical sensibilities. Jones is one of the greatest white rhythm and blues singers of all time--range, power, nuance, texture echo Otis Redding, Ray Charles and Solomon Burke with stunning ease and feeling--but he is incapable of just standing still and singing the notes.
He over sings this tune--too much melisma on a song requiring a less projective approach is melodramatic, not dramatic, and can seem silly although it is fun to hear Jones give an overwrought reading of the warning that the listener ought to be ready to cut their hair should things get hairy with the Man.
The swinging, swank, tight slacks wearing Jones, that guy who has to keep that pelvis in motion regardless of subject matter, mood or prevailing fashion and decor, gets down with The People! Odder things have been aligned, I guess, but not many. Interesting band reactions as well; David Crosby looks amused and looks to be suppressing a snicker, while Stills sounds inspired by Jones' gospel inclinations to be a soul man himself. Neil Young appears thoroughly unamused.
