Friday marks the 50th anniversary of the release of The Beatles' 'Sgt. Pepper's Lonely Hearts Club Band' album. We mark the event with alternate takes and covers on today's MEDICINE BALL CARAVAN on KRVS (11am-noon Central Standard on 88.7FM locally or at krvs.org). Also: great new tracks by The New Pornographers, The Viatones and Procol Harum. Plus some Richard Orange, Tomorrow, Traffic, Fifty Foot Hose and more.
