THE PERFORMANCE BY Sister Mary Norbert, the Javelin-Throwing Nun, previously scheduled for 7:00 tonight at Heptagon Gardens, has been canceled. Following last night’s performance, the diocese reached the decision that Sister Mary Norbert’s talents would better serve the Church in some other field of endeavor. The management of Heptagon Gardens apologizes to patrons for any disappointment or inconvenience, and would like to extend sincerest best wishes for a speedy recovery to the bishop.
