LIVE MUSIC: Parenthetically named '80s pop outfit Was (Not Was) is known for the song, "Walk the Dinosaur" And that ditty? Went a little something like this: "Open the door, get on the floor/Everybody walk the dinosaur/Boom boom acka-lacka lacka boom." Bring your favorite Gen-Xer to hear them live at Cafe Du Nord. *FILM: Just in time to make you feel less bad about being single on Valentine's Day is Woody Allen's Annie Hall.......
