If this were a previous season of The Sing-Off, I would’ve liked their “Let It Be” choice for a 60s revival. But now, it sounded like the big group sing number that opens the show. They tried to do too much with it. “Let It Be” is such a simple song, which is what makes it such an anthem for all time. So when you start raising big, choral voices behind a straining, emotional lead singer, it starts to sound gospel (I wrote that before Shawn Stockman said it, btw …for the record) and …well …I like some dancing and choreography with my a cappella.
