Newest edit, to be easy on myself: "button your lips" - that's rather bad, imagine... I think this induced my thus biased thought that The Rolling Stones still exist as a band that clings together because it's a most disciplined group. The individual, in that case the singer, Mick Jagger, is not even brought to his limit - that's the way I see AC/DC, the singer must beat the guitar - but "must not" even step forward from what must remain some background vocals, I dare say. No wonder, for compensation, Jagger is allowed and fostered in having his moves, bodily to see on stage, and what's more, it's an art not to if you could and can do. Yes, they can.
