If you don’t read John Fea’s blog everyday, you’re missing out on gems like this recording of Johnny Cash at Explo ’72, a Campus Crusade event that has been dubbed “the evangelical Woodstock.” Billy Graham spoke, and featured artists included Love Song, Larry Norman, Randy Matthews, The Archers, Children of the Day, Johnny Cash, and Kris Kristofferson. (Kris Kristofferson? Really?) Take a listen, and start reading John’s blog daily.

YouTube has a whole bunch of Explo ’72 recordings here.
