Monday's MEDICINE BALL CARAVAN on KRVS (11am-noon Central Standard on 88.7FM locally or krvs.org) prepares for this week's tapings of Etown Live at the AcA with recordings by Ann Savoy, Kelli Jones-Savoy & Megan Brown, Michael Doucet, Dirk Powell, Tiffany Teddy Lamson and Sonny Landreth. Also: new & recent tracks by The Cat Head Biscuit Boys, Sabra & the Get Rights and FeuFollet. We also give a nod to the birthdays of the late John Lennon and John Entwistle, too.
