Talented grandson Sam Woolf put a subtle spin on John Mayer's "Waiting On The World To Change." He's so young, but he seems like he's already an artist. We got back-to-back doses of Adele from hometown standouts Keri Lynn Roche and Ayla Stackhouse. C.J. Harris took on Ray LaMontagne's soulful "Trouble" on his guitar and gave a performance that was even stronger than his initial audition. Jennifer Lopez stood up and then said, "That boy can sing," after shuddering off her goosies. In an evil/genius move, the judges had C.J. step forward - and all the people in the front line probably assumed they were safe. The judges then had him step back and announced that the back row is going through. That meant that Kerri Lynn and Sam are also though, but sweet Ayla is heading home...which is just a few blocks away.
