Watch StreamingCommunity. If ever there’s a moment that brilliantly and perfectly illustrates the star-power possessed by Diana Ross, it is the opening of her 1978-1979 stage show, captured on tape for this Home Box Office television special. Beginning with the star’s face projected on a large screen, mouthing the words to her #1 hit “Ain’t No Mountain High Enough,” the scene cuts to Miss Ross (draped in furs and jewels, of course) sauntering down a white, almost surreal staircase. At the bottom of the stairs – during the joyous, climactic crescendo of the song – she suddenly bursts from the screen and onto the stage, greeted by the screams and cheers of an overwhelmed audience. Those lucky enough to be at these shows literally watched a superstar come to life before their eyes; incredibly, the impact is equally great when watched on a television screen decades later.
