This week, one of the brightest stars of the Texas Country/Red Dirt scene, singer-songwriter Wade Bowen, examines “Me and Paul,” Willie’s 1971 chronicle of the road-warrior life he was sharing with his erstwhile partner in crime, drummer Paul English. It’s a perfect song for Wade to get into, partly because, as he rightly points out, Willie was a progenitor of the circuit where he makes his living now, but also because of the setting for our visit: Wade zoomed in from his tour bus, which was broken down somewhere in Iowa on his way to a gig.
