Keith worked with me as my technician at South Luton High School. We lost contact after he retired and I retired the following year. He was a very clever man and a gentleman! I learnt a lot from Keith and he was an asset to me and all the pupils. He gave his time freely and was always prepared to help and support everyone. I did a search for Keith and found this site, I I am sorry that I was unable to make contact with him sooner. My thoughts are with you all. Graham Davies (gdaviessains@yahoo.co.uk)
