Seeing double? You were if you paid attention to the musical acts on Thursday’s late-night talk shows. One live song was not enough for Jenny Lewis, who performed both Red Bull & Hennessy (above) and Wasted Youth (below) to showcase her brand-spanking disc On the Line for Jimmy Kimmel Live. Not to be outdone, electro gadget guru Robert DeLong delivered Favorite Color is Blue (with the help of rapper K. Flay) and Long Way Down on Last Call With Carson Daly. Even The Tonight Show Starring Jimmy Fallon got into the double-play action with a medley of Get Ready and Ain’t Too Proud to Beg sung by the cast of the Broadway jukebox musical Ain’t Too Proud: The Life and Times of The Temptations. Check ’em out below. On the double, of course.
