Last night, Liam Gallagher and his new band Beady Eye made their american TV debut with a visit to the Late Show with David Letterman. Bringing the swagger that only Liam can pull off (and it's only because he's had it going on for the best part of two decades!) the band put in a performance of their track "The Roller". The track featured on their debut release Different Gear, Still Speeding. Check out their performance at the top courtesy of The Audio Perv.
