This TV Show Ad for a Live Music Show Treats the Public with a Flash Mob

This interactive TV show ad for Bosca Ceoil takes place in a public square, challenging people to come forward and turn a crank for a "life effect."

Once turned, various people playing instruments start appearing to create a flash mob playing live Celtic music. When the group gets pretty sizable, it also manages to draw quite a crowd. However, there's a security guard that shows up and gets the music to quiet down. But moments later it seems that he's in on the whole thing, since he picks up an instrument and gets the music back up and going again, which makes the crowd gathered in the public square happy once again. Since Bosca Ceoil is a show that's based around high energy and live music, this is a clever way to simulate what you might expect when you tune in.
