Flash opera mob!
How perfect is this: Public market, Italian festival, and Verdi.
Thirty members of the Opera Company of Philadelphia breaking into the “Brindisi” from La Traviata. Best part is all the expressions of delight once people realized what was going on (well, except for the one dude on his cell who looked annoyed, plugged a finger into his ear, and kept talking. No soul whatsoever.)
I LOVE it. What a great idea. Thanks so much for posting!
