As far as singer-songwriters go, it doesn't get any better than the legendary Carole King, the subject of the new Broadway musical Beautiful. Actually, the only thing that could make a live perfomance from King any better is the addition of fellow ivory-tickler Sara Bareilles, which is exactly what happened at the 56th Grammy Awards telecast. Bareilles, who was nominated for two Grammy Awards including Album of the Year, performed her hit song "Brave," alongside King, who opened the performance with a rendition of her song "Beautiful." The rest was musical magic. Bonus: the duo was introduced by Tony and Grammy winner Cyndi Lauper! Check out the performance below!
