Ken Erlich and Neil Portnow have put together a sensational Grammy show tonight. I’ve looked over the list and — aside from “Downton Abbey”–this is the show to watch. Taylor Swift opens the show with “We Will Never Get Back Together.” There are tons of hit performances from The Lumineers to Maroon 5. And the Sting-Rihanna-Bruno Mars medley is a tribute to Bob Marley — wait, I don’t want to spoil it. Plus I’m told the tribute to the late Levon Helm will bring you to tears featuring Elton John in one of his two spots tonight. Stay tuned for updates here and on Twitter @showbiz411.
