BYU’s male a cappella team Vocal Point earned their spot in the final six groups on NBC’s “The Sing-Off” through their performance Monday night. Judges and the studio audience loved their dynamic and hip-swinging medley of Elvis Presley hits.Dressed in classic jailbird stripes, the group paid tribute to the king of rock ‘n roll with a medley that concluded with a rousing interpretation of “Jailhouse Rock” after kicking off with “Don’t Be Cruel.” In between, their performance of “Can’t Help Falling in Love” stood out for its sincerity after lead vocalist Jake Hunsaker said, “We want to dedicate the second song to the women in our lives who are putting up with our absences.”
