Sad to hear of the death of actor and painter John Cairney.
Does anyone remember a BBC Scotland drama series in the mid 1960's about an inspirational science teacher in a fictional Scottish comprehensive school? The teacher was played by a youngish John Cairney and it was called "This Man Craig". Apparently 52 episodes were made but only two survive in the BBC archives. Sad. I remember being inspired by it and watching with my parents as a 9/10 year old. I think it was quite gritty, depicting "modern" problems of the time. A sort of Scottish version of Z Cars but based in a school.
