Spirit of 1898

Philadelphia offers many chances to stand in historic footsteps, but the best may be on the USS Olympia, Commodore Dewey's flagship during the Spanish-American War. The place is clearly marked where he stood for the May 1, 1898, attack on the Spanish fleet in the Philippines and gave the order "You may fire when you are ready, Gridley" to the ship's captain. Where did Gridley stand? Find out when the Manila Bay Weekend commemorates the event with the living history crew giving tours of the cruiser, docked at the Independence Seaport Museum, 211 S. Columbus Blvd. Times: Noon to 4 p.m. Saturday and Sunday. Tickets: $13.50; $10 seniors and ages 2 to 12; 2 and under free. Information: 215-413-8655 or www.phillyseaport.org.

The love goddess

Comedian Judy Tenuta has an eccentric, egocentric take on life - what else would you expect from someone with her own religion ("Judyism")? Plus, she plays the accordion, and that's always cool.
