Hi Petunia,
What a coincidence regarding the music. Although I went to Stoke Junior (Briton Road), and not Stoke Heath, in the infants' school we were also led in to Grieg's "Morning" on the record player, and whenever I listen to it over 45 years later it still transports me back to those fun, innocent days. I'm fairly sure they also occasionally played Mozart's Eine Kleine Nachtmusik, because that also still has the same effect!
A memory that still haunts me, though, is that as a shy five year old, standing there in assembly, I was too timid to put my hand up in front of everybody and ask to go the the toilet - so I held on as long as I could before warming up one (or both) of my legs!
It was obviously not an uncommon occurrence though, as when my kind teacher, Miss Riley, took me back to the classroom, she opened a cupboard full of spare pairs of shorts!
