The culty British singer-songwriter Robyn Hitchcock has had a long, fascinating career. He led the Soft Boys, the influential UK psych-punk band. He filmed a concert film with Jonathan Demme and then acted in a few other Demme movies. He served as a key inspiration for bands like R.E.M., who covered his song “Arms Of Love.” Along the way, Hitchcock also cranked out an insane number of glittering power pop nuggets without ever getting anywhere near mainstream stardom. Now, he’s telling a key part of his story in a new book.
