Writers Amy Tan, Dave Barry, Ridley Pearson, Stephen King, Scott Turow and Mitch Albom, Maya Angelou and Roy Blount Jr have a band called the Rock Bottom Remainders. “They are what every garage band dreams of becoming: a bunch of middle-aged people with word-processing day jobs who every now and then get to go on tour, not in a rented van but in Aretha Franklin’s old bus. They have played benefit concerts all over the country, before live, paying audiences, and even have groupies.”
