I've watched this video a lot. This time, I became intrigued with the way Richie plays guitar. He uses his thumb, not fingers, to form the chords.
And in this, his Woodstock performance of "Freedom," largely improvised because he had to hold the stage for three hours while the big-name acts made their way belatedly to the festival, he seems to do the same.
Here, not so much.
No matter how his fingers fly, Richie pours all of his heart and mind into that instrument.
