Bill Murray used to do a very funny routine where he was the sleazy piano bar musician playing inane tunes and urging a sing-along to an audience which was oblivious to his kitschy banter. Do you know the words to the music of Star Wars? We all roared with laughter. But my mother had a very different reaction. Having a great deal of experience in small piano bars, she saw Murray as the quintessential loser struggling to remain relevant: he wasn’t funny; he was sad. My mother didn’t like Bill Murray … he was too real.
