Michael is at the climax of his fame & talent, just before the downfall.
He joins for a mere 1 minute, full of falsetto voice, copyrighted “whooo oooo” & moonwalks.
Then Princes comes (& Michael lives). Purple Rain era.
He plays the guitar for a short funky jam, leads the band who follows his signs, have a few sexy poses, James Brown style screams & dance steps.
More than a Prince style jam, it’s a James tribute.
All the difference between those 2 guys is there, Michael is one of the greatest performers of this period, Prince was a great performer AND a wonderful musician (& still is, see below).
