I recall booking Derek and Dorothy when I ran my club. We had an excellent night and subsequently a friend from Australia and myself visited them when I took him around the country on a sightseeing trip. Dorothy gave us a lovely home cooked dinner and we were put up in their caravan to spend the night. I have, of course, added Dorothy to the "In Memoriam" thread and send my condolence to all those who know and love her. RIP Dorothy.
