31:12 of song and conversation on World Cafe Live with David Dye.
As an aside, it’s pretty cool for me, in reading and listening to interviews re: the birth of “The Ghosts of Highway 20” is that I, along with several of the FF contingent, were in attendance at The Cox Capitol Theater in Macon, GA where Lu revisited her past AND then heard the song for the first time when she performed with Roseanne and EmmyLou in Nashville. Goosebump stuff for me.
