Teachers from Harwich and Dovercourt High School are the latest to become an internet hit with an end-of-term goodbye video.
Staff strutted their stuff all around the school to a soundtrack made up of Happy by Pharrell Williams and Wrecking Ball my Miley Cyrus.
The nine-minute video has more than 1,000 hits on Youtube.
Michelle Causon organised the stunt, which was played at the traditional leavers’ assembly.
She said: “We got a few of the old teachers involved and then more and more people wanted to take part.
“On the last day you can hear it playing all through the corridors.
“It probably takes about six weeks to film the whole thing because you have 80 members of staff with work to do but it is worth it in the end.”
