We got Mamma Mia on DVD for Christmas, and it seems to have been the best thing ever. Daphne and I have now watched it 2 times through. We have been listening to the soundtrack since September, so she really knows all of the words to the songs, and when I play it in the car, I catch her in the rear view mirror rocking out and singing "Gimme Gimme Gimme.." or some such lyric.
We finally watched the movie again tonight with Daphne, and she was literally screaming while they were doing the hen party. She was jumping up and down on the couch running around so excited.
And so, just like her mother, she is a huge fan of Greece, Abba and Mamma Mia. Go figure. Like mother like daughter.
