You filled in a load of forms (stating parental income/mortgage/outgoings &c.) with your local LEA (council) who then worked out how much maintenance grant you got. Some students got the full amount. Can't remember the figures now, 30 odd years ago for me...But way back, wasn't there a tax rebate for parents that would cover the grant? I remember a colleague telling me about this. That would have been in the 70s I guess.
The Japanese fashion designer, Kenzo Takada, has died of Covid-19 at 81. I had a couple of Kenzo shirts in the early 90s, just before he sold the brand to the LVMH Group. Very bright. I was hanging on to the 80s back then.
