"What did Mike Nichols mean when he said "ABBA" gets the Sea World crowd? Am I hearing him correctly? If I am, it's sort of insulting/dismissive, especially because the show is called "Mama Mia.""
I believe he meant that Mama Mia is a fluffy show based on Abba songs. Fluff is the same sort of stuff you get at Sea World.
David walked into the valley
With a stone clutched in his hand
He was only a boy
But he knew someone must take a stand
There will always be a valley
Always mountains one must scale
There will always be perilous waters
Which someone must sail
-Into the Fire
