The word that came to me immediately after listening to this video was simply "WOW!"
'Ode to Joy' also known as 'Beethoven's Symphony No. 9', was written by German composer Ludwig Van Beethoven in his later years when he was mostly deaf.
Ode by the way means, "a lyric poem in the form of an address to a particular subject, often elevated in style or manner and written in varied or irregular meter" or "a poem meant to be sung."
In fact, it was originally a poem written by Friedrich Schiller who was a German poet, playwright, and historian, though it was adapted later by Beethoven http://www.en.wikipedia.org/wiki/Ode_to_Joy

On the 130th anniversary of the founding of Banco Sabadell, a number of people wanted to pay homage to Sabadell, a city in Spain with a flash mob consisting of 100 people from Vallès Symphony Orchestra, the Lieder, Amics de l'Òpera, and Coral Belles Arts choirs (as shown in the video above).
Here is a version that sticks out in my mind from years ago, from the movie Sister Act 2, with Whoopi Goldberg as one of the main actors:
This musical piece is seemingly popular during the Christmas season, though with differing variations of lyrics, one of which is as follows: http://www.lyricsfreak.com/s/soundtracks/ode+to+joy_10220943.html
byoV (short for 'bring your own voice'), the community choir that I sang with sang a somewhat similar version for our recent Christmas concert. It was a lot of fun for us choir members as well as the audience who heard us. How can it not be when you add a little funk, soul, and rap into it? Ok, that's my interpretation anyway! ;)
There is nothing like music bringing people together now is there?
