Shot in tasteful monochrome, the secondary teachers perform with admirable gusto and a great willingness to laugh at themselves. We particularly like the Dizzee Rascal-style rap by John Salberg, a PE teacher.
At last viewing (and there have been many in the TES office), it was one of the top-rated videos in YouTube's UK music charts.
We hope that teachers across Britain will visit the site, give it a five-star rating and make the track a Christmas number one.
Unfortunately, when YouTube is bad, it's very, very bad. Witness the 22-second offering from Ed Balls, education secretary, and Gordon Brown, to accompany last week's Children's Plan. The two stand on the steps of No 10 with a group of children, grinning inanely. And, er, that's it. Our Whitehall sources blame a "technical hitch".
