'Mama,' Meryl, musings

Got a little excited when I saw the Mamma Mia! trailer in a movie theater recently. With the success of Hairspray last year, it looks like summer is becoming the season for frothy stage musicals turned silver screen tuners.Here's one of the trailers. I like this one because it actually shows Meryl Streep singing.Here's the trailer I saw in the theater:Aaargh! The tyranny of ABBA! Why is that music so fun? Mamma Mia! the movie opens July 18.
