American Idol season 22 Top 10 contestant Kayko gained a huge fan following during his run on the show, and he’s been very busy with his music career ever since. Kayko, whose full name is Sam Kelly-Cohen, didn’t originally intend to audition for American Idol. Instead, he was the piano accompanist for his friend, Abby Blake, but the judges–Lionel Richie, Katy Perry, and Luke Bryan–asked him to audition as well. He wowed them with his beautiful original song, “Time of Your Life.”
