As for the Journal review...

"...It's an interesting illustration of the power of art to disengage critical thought. For an encore, Waters did "Another Brick in the Wall." Probably not too many middle-age Pink Floyd fans would endorse Waters' view of public education as an instrument of oppression, but put it in a catchy chorus, and 23,000 people sing along."

Right you are. In much the same way, if you would find yourself at a Sir Mix-a-Lot concert, you might see thousands (OK, couple hundred) of poeple sing "I like big butts and I cannot lie..." who, in actuality, do not like large posteriors.
