Lady Gaga and Spinal Tap: Degrees of separation decreasing

GLAM ROCK, how soon we forgot about you.
I bemusedly watched E! Network reporters marveling at the "never-before-seen" arrival of LADY GAGA at the Grammys last night.
I don't think I'm alone in wondering: How was her "outrageousness" any different or more outrageous than ALICE COOPER'S height of infamy?
"Who's Alice Cooper?" KERSTIN just asked.
"The snakes? Schoooool's out for sum-merrr!"
Now she remembered.
Not many other people remembered, I guess.
Wasn't it once said that people who cannot recall history are doomed to repeat it? It applies to pop stars in plastic eggs, too.
By the way, SPINAL TAP did the emerging-from-the-plastic-pod thing with so much more panache.
