In the days before multimedia, there was BBC schools radio. "Music And Movement" was their public service to avoid P.E. teachers going into meltdown under the strain of ever having to have a single fucking idea, ever. Jonathan Cohen-type piano music and, for P.E., strangely soothingly-voiced routines of the "I'm a tree, I'm a tree, be a tree with me" kidney. The sort of things you could do without needing special P.E. kit, which is why to this day Debussy-type plinky-plonking takes me to the scary visual place of Paula Marshall in her tights the colour of diarrhoea. Manufactured in that colour, I mean. But even so.
