They're getting tougher as the millennium approaches. Nobody got all three right last week, but as we are feeling generous, we are sending champagne to Christopher Richards of Lawrence & Wrightson in recognition of his courageous, and almost accurate, attempt. The correct answers were: alto king Charlie Parker; the Paolo Alto Memorial Church at Stanford University; and Alvar Aalto's Experimental House. Answers to this week's puzzle should reach us by Monday am. Send a postcard (the more surreal the better) to AJ Astragal, 151 Rosebery Avenue, London EC1R 4GB. In emergency fax 0171 505 6701.
