they were/are Keith Plumridge and Paul Winder.
Last I heard of Keith was when he was working on coasters in Australia but I think he returned to the UK.
Paul never got his ticket, main reason was that no one could read his writing so he flunked the written tests all the time. Last I heard of him he was living in the Dorking area, Surrey.
Would be great if someone could update me on these two former students.
