A group of friends who left King Edward VII School 60 years ago decided to keep in touch - and they have done every year.
In recent times, the unofficial Old Boys reunion has been held at the Rising Sun pub in Bamford, combined with a walk in the Peak District and dinner.
But the diamond anniversary was celebrated with tour of the Glossop Road school led by headteacher Beverley Jackson.
It was the first time the former pupils had seen the redeveloped premises.
“We were amazed at the difference,” said organiser Reg Hobson, aged 79, a retired civil servant, of Fulwood, one of only three in party of 12 now living in Sheffield. One of the group came with his wife from California.
Initially there were 30 who kept in touch, and Reg is now in contact with 15.
They were “very happy” days, he said. “We all had a good time.”
The Old Boys looked at the school records for 1953, met the school archivist John Cornwell and talked to current students.
