On Sunday, lots of kids, little ones and grownups, will pay tribute to their dads on Father’s Day. For Music Thursday, Eight Forty-Eight talks to Jeffrey Brown, a cartoonist and author of Darth Vader and Son, a graphic novel that explores an alternate universe in which Darth Vader is the father we always wanted him to be. Brown, along with Richard Steele and host Tony Sarabia, pick some tunes about dads: the good ones, the deadbeats and the many in between.
