Friday night. Manhattan. Strolling home. Sean Penn. Madonna. Overheated photographers. Rumble. Another one. Motivation? You kidding? Joint celluloid debut, Shanghai Surprise, declared a dud. Followed by three-day stint in David Rabe's play, Goose and Tomtom, only friends invited. Good thing. Word on the street: wouldn't play to a paying crowd. You'd spit too. Roll the tape.
