Beethoven yan Nanay

I was watching a video which I posted on my FB wall earlier tonight. Just before bed time and then called the little girl to watch and listen with me. Its a flash mob somewhere in Europe... a little girl gave a coin to a street performer who had a cello...later join in by a full orchestra and the music is so familiar and an eternal beauty ...can't say what it was... and the little girl got really excited-- it's Beethoven Nanay-- I heard it from the Little Einsteins.
