I've seen a few good ones. I've seen a few not so good ones...
Mostly, I love the surrealism of spontaneous song in a place where it doesn't seem to fit.
A friend of mine posted the link to a flash mob that was performed at a wedding.
It gave me chills. It made me tear up.
Though I have never seen Le Miserables on the stage, I grew up with the music in the house because my parents had seen it and loved it. I'm looking forward to the movie coming out later this month.
So, really, more than anything, this is for my Mom.
