I remember David Algar very well. He had an amazing memory for names. He used to be our CO when I was a lad. I saw him 20 years later and he still remembered my name!
My favourite was Brent Smith; a very funny Yorkshireman who was fond of a practical joke or two and gave a fantastic rendition of Jesús' parable of the man who sold everything for a pearl of high value... "even his three-speed donkey he had in the garage!"
Richard Gillam was a giant and drove like a madman (something that greatly impressed me as a young man in my twenties, especially when he did a handbreak turn in the middle of a busy high street.)
Assemblies are definitely not the same nowadays. They were so much fun in the 70s/80s to be able to explore the convention footy grounds even as young kids: Sheffield Wednesday, Notts Forest & County, Dudley Assembly Hall (with sneaky trips across the road to the zoo.)
Nothing beat a bacon buttie and coffee first thing after arriving when you'd been up since 6am to catch the bus.
