I find the ploddy rhythm hymn-like. Something religious-sounding about the changes. It’s actually fun to play because the chords are doing all the work, so you don’t have to play complicated melodies or bass lines. This is not funk. Just make sure the chord progression is played slightly ‘swung’, that is, not on the beat but just before the beat.
The chords or changes for the intro are:
F C/E Dm Dm/C Bb Bb/C C7 F
Outro (the ah ah ah bit)
Bbm Bbm/Db Eb Ab Ab/C Db Bbm Bbm/Db C F
