I don't know if any of them will succeed. At least "The Producers" and showgirls in it.
"BKLYN", oh please...
"Spamalot" might, but I doubt it somehow.
The only show that I think will be like "Mamma Mia" when it gets to Las Vegas will be "Jersey Boys".
Because like "Mamma," it's score asks nothing of your brain and feels like an old friend.
