The camera was attached to the railing outside the wheelhouse of the tug boat.  During the finale someone hit the camera and knocked it around, during this time you get to see us shooting the show for a few frames.  I shot half the show, another person shot the other half.  The other people on the barge were the show Operator (one in charge), a person keeping track of timing in case our radio link failed (we were synchronized to the music heard on shore), and the tug deckhand who was in communication with the captain.

The pause in the beginning WAS scripted, there were announcements during that time.  I don't know what they were, all I hear in my headset is "Fire 1, Fire 2, ...".
