When I was a kid in the 90s Manchester Music Service (part of the council) would lend you a musical instrument for free if you had lessons from them. I don't know if the lessons cost or not (my parents would have been able to afford it if they did - I'm not trying to claim Working Class Cred), but certainly you didn't have to pay for an instrument.If your parents could afford a piano, guitar, and lessons for both I’m not sure how working class you were.
Today that’s £70 a week on lessons for one child.
