After walking on stage, James Brown would take off his jacket before even getting to the mic stand.
Was he cold and then got too hot?
Did he suddenly decide he didn’t like it?
Maybe he just forget to take it off in the green room?
No.
If he didn’t start with the jacket on, then the people wouldn’t be able to see him take it off. And what does taking off a jacket signal?
It’s time to go to work.
