Conan O’Brien marked his return to late night television last night with the debut of his new show Conan on TBS. O’Brien’s good friend Jack White of White Stripes and the Dead Weather fame dropped by as the show’s first ever musical guest. Together they performed Eddie Cochran’s 1957 rockabilly tune “Twenty Flight Rock,” with White appropriately turning to his Gretsch guitar for the number.
