The sad thing about how Elvis did his tours is it did help put him in an early grave. I think that is one reason why other artists today don’t have the schedule that he had because they know it’s not healthy or wise for long career. After all he wrote the book for all other entertainers to follow.
Speaking of Beyonce her super bowl performance was so theatrical just like all of these other entertainers that use a 100 dancers and lighting to create excitement. They can’t entertain an audience like Elvis could by himself. He didn’t need all of that.
