Forget the nominees. This year, the Grammys are finally doing it right. It’s a celebration of the world of music. They’ve just announced a Beach Boys reunion with Brian Wilson, Al Jardine and Mike Love. Add to that performances from Paul McCartney, and Bruce Springsteen and the E Street Band. That would be enough. Dayenu! But of course Adele is performing, and so are hot new groups like Foster the People, The Civil Wars, and (less newish) Maroon 5. Chris Brown is going to be incredible — it’s time to move on from his troubled past. Diana Ross, who gets a Lifetime Achievement Award on Saturday night, is a presenter. Carrie Underwood and Tony Bennett are performing together. The show sounds like it’s going to take five hours. But it will be worth it. There’s a rumor that Lady Gaga is opening the show. No word yet on Van Halen. LL Cool J is hosting. All they’re missing is Lana del Rey (just kidding!)
