Hi
Outside pic of the Super Swimming Stadium :
http://mgs1970.netfirms.com/photo_page7.htmI am also 57. When I was 12ish an annual season ticket for the S.S.S. cost 10 shillings. We used to leave school at break time (say 10.30) and cycle to the pool on the first day of the season to try and get the season ticket with the lowest number. I got 5 one year, but someone's mother worked in the office, and I think he raffled the lower numbers !
It was also a tradition to swim a breadth on the first day they were open (1 week before Easter ?). I remember seeing 47F (8C) one year.
Even in summer, 67F was common, and 73F (23C) was seen as tropical. These days, I'm not too happy swimming when it is under 26C. Living here, most pools are around 30C in summer.
