Many people left many things at the F Street 9:30 club. Perhaps Tony Bennett really did leave his heart. How else to explain his appearance at the new venue? Whatever reason for the Precambrian crooner’s continued flirtation with his grandchildren’s peers, his pipes still communicate the strength of the American standards canon, and witnessing that is an experience worthy of telling your grandchildren. At 8 p.m. at the 9:30 Club, 815 V St. NW. $25. (202) 393-0930.
