Courtney Love charmed a small group with an impromptu performance at the Woodward tavern in Boston’s Ames Hotel. During her acoustic set of five songs the other day, she drank Voss water, wore a large floppy black hat and kept asking her assistant for cigarettes. Love told the 20-odd lucky guests that she wanted to do more acting and spoke highly of Boston, calling it a “very intellectual town” and mentioning she had a good friend at Harvard — which she also referred to as “H-Bomb.”
