Persistent earworm alert XIX

An early '70s groove has lodged itself firmly in my mind this morning.  The artist co-wrote and sang backing vocals with James Brown.  You'll probably pick up on that right away, as the song that keeps playing in my head is heavily in Brown's style.  Its recurring riff sustains it until it ends abruptly.  The repeated vocals work, although any number of lyrics could likely be sung over the rhythm without compromising it.  The tune?  Bobby Byrd's "I Know You Got Soul."  I first heard it while driving and found it creeping into my mind today while listening to other stations, even news-talk ones.  That's a riff with staying power.
