In 1990 the charts were full of bands espousing working class angst and northern soul.It suggests the main reason for this is the cutting of public funding for music lessons - steady on, Mail, you're starting to sound like you're pre-May Liberal Democrats or something.
But some twenty years on it seems that it is British public schools that are delivering the pop stars of the moment.
A new survey into the heritage of modern musical acts has found that 60 per cent of acts in the charts today - attended public school - compared to just one per cent two decades ago.
There is the another possibility, though, that it's just become more respectable for posh kids to be in bands now.
Also, back in 1990, the charts felt a lot older - Maria McKee, Madonna, Cliff, Paula Abdul, the B-52s, Elton John. Could it be that bands aren't actually getting any posher, but they're having hits younger, and so the kids who in 1990 would scuff about for a couple of years, go 'sod this, I'm going to call Uncle Barney and get a job at the merchant bank' are actually being successful before their trust fund manager threatens to cut them off?
