Today’s Boston Globe reports on Paul Green’s new School of Rock that is opening in Watertown. (Fine writeup except for a sad, little “more cowbell” joke.) They are accepting up to 180 students aged 7 to 18 to study guitar, bass, drums, keyboards, or vocals for 12 weeks. The youngsters will expand Watertown’s rock numbers, joining the likes of Grizzly Bear who recently recorded their latest album here. For those kids about to rock H2otown, we salute you.
