[Watch] Tenacious D - "The Roadie" x "Beelzeboss" Live on Fallon

Yesterday we saw Tenacious D perform "The Roadie" on Letterman, today we get to enjoy the duo perform not just that track but "Beelzeboss" too. KG and JB performed the tracks from Rize of the Fenix during a visit to Jimmy Fallon's late night slot. Check out the lead single up at the top with "Beelzeboss" being up for your enjoyment after the jump.
