Country icon Willie Nelson has a new record out today called Heroes, which finds the red-headed stranger covering songs of, well, his heroes, and offering up a few new tunes of his own. Last night he took to the stage of Late Night With Jimmy Fallon to cover Pearl Jam‘s “Just Breathe,” fronting an eight-piece band that prominently featured his 23-year-old son, Lukas. The song comes from PJ’s 2009 album Backspacer and not Ten or Vitalogy or any of the grunge titans’ earlier work. We can’t help but think that it would’ve been killer to hear him utter those lines, “Jeremy spoke in class tuhhh-day.” Maybe one day.
