Love Streep's singing voice (love that she gets cast in countless musicals), love the movie MAMMA MIA to death, I'd be there opening night even if it ends up being the SEX & THE CITY 2 of the year it comes out... Streep will never do it though, unless they can get everyone else on board.
"Some people can thrive and bloom living life in a living room, that's perfect for some people of one hundred and five. But I at least gotta try, when I think of all the sights that I gotta see, all the places I gotta play, all the things that I gotta be at"
