I'm old enough to not only have seen many of these classic entertainers, but to have seen them in their prime.
Each was an original, like James Brown and could light up an audience.
People were hungry to lose their inhibitions and be swept away by the talent.
James Brown had "moves" and bits that were so original and unique that it was stunning. Same with Elvis, Jerry Lee Lewis, Johny Cash, Ike and Tina Turner, the Beatles, the Who and the Stones.
Rock shows would have over 6 different acts. Was really something to see.
