I would have loved to hear him sing this cover of Stevie Wonder's song. With some "Michael Jacksonese" ad-libs thrown in there, of course.
Or this one:
I always thought he said "Just look over your shoulder, honey !" in "I'll Be There", until I heard and read "Just look over your shoulders, honey !" in the great and new Busta Rhymes (featuring Kendrick Lamar) song/music video called "Look Over Your Shoulder". Thank you, Busta ! :)
