I’ll be on The Big 550 KTRS/St. Louis today 3-6pm CT, and in my first hour I’ll talk with Jeff Lujin, director of a new documentary about the 1974 Ozark Music Festival, which had an incredible lineup of acts, a crowd of more than 250,000, and enough problems to ensure that the festival never happened again.

Also this afternoon: Colin Jeffrey and I will review “Hercules” and “Lucy,” and I’ll have a new batch of Knuckleheads In The News®, plus your chance to play my Harris Challenge trivia game. You can listen live over the air, via the free KTRS smartphone app, or stream it here.
