I remember 'Sir' as I used to call him from my days at Harriet Costello School in the 80's. He was my favourite teacher and I have had fond memories ever since. I had always hoped that I might have bumped into him over the years but it wasn't to be. I'd like to send my regards to Mrs Francis - she might remember me - I used to be a menace in her maths class. Best wishes, Simon Aldridge.
