LOS ANGELES (AP) – The latest argument for music education: several “American Idol” contestants weren’t familiar with The Beatles. Burnell Taylor didn’t know “Let It Be” before he performed it on last night’s show. Amber Holcomb had never heard “She’s Leaving Home” before she sang it. Lazaro Arbos says he had to learn “In My Life” at the last minute because of a song switch. The judges reduced Arbos to tears, and the show came back from commercial with Ryan Seacrest asking the judges to justify that. They weren’t so hard on everybody, though. They loved Angie Miller’s rendition of “Yesterday” and Janelle Arthur’s version of “I Will.” Mariah Carey called Kree Harrison’s performance of “With A Little Help From My Friends” “fan-freakin’-tastic.”
