They will talk about this finale for years

The surprise act at the end of the Variety Show included a group of
teachers rocking out to the song "Old Time Rock N' Roll." To set the
stage for their act we used some fog in a can. We had tested it before
hand and used it in the opening number but this time the fire alarm
went off after spraying some backstage. The fire alarm occurred right
in the middle of three first graders dressed as angels singing so
sweetly. The kids were so efficient and calm when it came to getting
out of the school. The whole school had to evacuate and wait for the
fire department to arrive and clear us for re-entry. There were at
least 8 kids from the show outside barefoot including Monti. By the
time we got back inside the kids had to catch buses to go home so the
teachers never made it on stage.
