As Mr. Matrix KEANU REEVES played his bass guitar and relaxed in a suite at the trendy Chateau Marmont on the Sunset Strip, he heard a loud knock on the door. He opened it to find two giggling teenage girls who'd seen him enter his room hours before and finally got up the courage to knock. They wanted autographs and kind Keanu signed room service menus. Noticing his guitar, the girls asked for a song (gutsy broads!) and he obliged with an original tune he'd just crafted.
