Rescheduled from May 7th to May 6th, resulting from a 4/24/81 New York Supreme Court injunction giving dibs on the area to the New York Islanders, who might have needed it for a Stanley Cup playoff game. Thanks to Jesse Jarnow for the specifics, which come from an item in the St. Louis News-Dispatch, 4/26/81, p. 3G.
