Cannabis-loving country star Willie Nelson was on the road again after canceling a concert last week due to “altitude sickness.” The icon was seen Saturday at the Austin premiere of “Lawless,” where he introduced the Shia LaBeouf–Tom Hardy film, which includes Nelson’s tune “Midnight Run.” A tour bus then whisked him to a gig in nearby Bee Cave, Texas. Also at the Alamo Draft House premiere in advance of tomorrow’s “Lawless” opening was author Matt Bondurant.
