SHUT-EM-UP-AT-THE-BACK SCHOOLATHON singalong symphony led by staid man and woman duo, formerly bubble-permed PETER COMBE and long haired trilly KATHARINE HARRIES, followed by various people and always the redoubtable JONATHAN COHEN. Simple, whimsical (quickly turning to annoying by fourth repeat rehearsal) tunes were conveyed by musical staves where the notes lit up one by one at the appropriate time. Kids in the studio were given amusingly menial tasks to do, like playing glockenspiels with just two notes on them. Kids in the school TV room were given not quite enough accompanying music score booklets to share and divided up by teacher into two groups while Cohen and chums played an interlude. Guaranteed to take place on the hottest day of the year in the stuffiest room in school. Still, the ultimate in class bonding, with brainboxes and dickheads alike united in their quest to hit the cowbell on the third beat of the fifth bar.
