You may have caught Shakira and Blake Shelton's cover duet of Lady Antebellum's "Need You Now" on the show, The Voice.  But, they performed it together live on stage at a Hollywood party and I think this version is better.  Better lighting and better sounding.  If you did see it on the nationally televised show, give this a listen, do you think it's better?  If you didn't get to see it, you're in for a treat!
