I did my first solo night nav in July 1974 during Grocer Heath's 3-day week/power cuts - and all the towns had their lights out! Flying a triangular navigation exercise across blackest East Anglia in one of HM's Jet Provosts with only Eureka 7 and one UHF radio meant one flew IAS, heading and time extremely carefully!
I had an 'Advanced Instrument Flying Grading' ticket - but no IR until 2 weeks later. I recall it being all rather boring.
