Music lessons in my schools (70s-early 80s) were largely a waste of time...
There was nothing in primary, just a bit of singing at assembly.
And in secondary we had music in years 1-3, 1 lesson a week. They consisted of Mr Bird playing some music (usually Young Person's Guide, or The Planets, or for a contemporary feel (!), Joseph and His Amazing Technicolor Yawn). Then folks would say if they liked it or not, though because he wasn't particularly good at discipline this usually meant him shouting above a general cacophony of rude comments. And then we'd do some very rudimentary theory. This theory would be tested at annual exam time. However, they discovered I had private piano lessons after I got 100% in the first exam (my mum's a piano teacher) so from then on I got different exams from everybody else - though this was usually about grade 1 theory when I'd already done grade 5... So music wasn't really a thing for us at school.
Though in 6th form, Mr. Q had the bright idea of forming a one-off band to play before a viewing of that banned anti-nuke film (wot I can't remember the name of). I played keys, Cossack played guitar and Mouse played his violin bass - someone rattled a tambourine in the background while we did a couple of BarclaysBankHarvest and Dylan songs. I was so fascinated by Mouse's bass that I took it up when I got to Uni - and strangely it turned out that the Hofner bass belonged to Mouse's brother, our very own @lurksalot!
