Basia Bulat and Ted Leo’s fantastic “Where Have All The Rude Boys Gone” aren’t the most obvious match. Bulat is a gentle folkie, but it’s probably fair to call Leo a folk singer as well, though far more fiery than that word usually implies. But Bulat, who frequently plays an autoharp, clearly loves the song. (As the song itself goes, “Someone sang me through it.”) We think you’ll like this version, too.
