Sir Cliff Richard struck an interesting note, commenting that he wasn't quite sure why he was there. "I mean, can a rock star be a pioneer?" he mused. He looked around at the crowd of performers, singers, mathematicians, horticulturalists, novelists, satellite technologists, politicians, etc., and I could see what he meant. Surely the old adage that "pioneers die and settlers prosper" did not fit many of the participants.
