Whether you be a cat or a kitty, you'll groove to Wednesday's MEDICINE BALL CARAVAN (11am-noon Central Standard on 88.7FM locally or www.krvs.org) as we spin to the sounds of the late T-Model Ford, David Egan, Caleb Elliott, Jimmy Robinson, Johanna Divine, Brother Dege, Jeff Lynne, Ollie Vee, A Funk Band Named Machete and the newest by Preservation Hall Jazz Band. Also: Mr. Robert Plant sittin' in with both Patty Griffin and classic Led Zeppelin.
