Well my DH and I have seen both....We've seen Mamma Mia here in DC and in Vegas....and Wicked in DC.....he's loved both of them and is always trying to ask me trivia about Mamma Mia.....of course he's a big Abba fan too.....I kind of agree with the poster who said if the guy is an Abba fan he'll enjoy Mamma Mia and if he's not he probably won't......
