Yes, I remember the heatwave of 1976. It was 35 degrees in the shade at the beginning of June in Copenhagen, and then I went off to Spain to take a three week course in advanced flamenco dance.
Three classes a day of nearly two hours each, starting at 8 a.m. til 1.pm break for lunch and siesta the back for the last class at 4 p.m. After that two or three hours practising on our own, for our teachers were used to the heat and made absolutely no allowances at all for it being hotter than usual.
I also remember the heat wave in, I think, 1960 - my mother said it was the first time she had ever needed to water the garden, living as we did in th west of Scotland.
We had some glorious hot and dry summers in the 1980s too, 1983 probably and '89, or '90, where we laid my friend's three month old baby daughter on a pile of towels on the floor with nothing on at all, as she had the most horrendous nappy rash. We had about six feeding bottles with boiled water cooling in the fridge at a time for Antonia and gave her one as soon as the previous one was empty.
Rinsed the wetted towels, scalded them and hung them out - they were dry in five minutes and back on duty.
