LOS ANGELES (CBSLA) — The 62nd Academy Awards show kicked off with an upbeat performance by Janelle Monae, who donned a red sweater for a cheery performance of the “Mister Rogers’ Neighborhood” theme song, before taking a more political stance.

“It’s time to come alive,” sang Janelle Monáe in the show’s opening number, “because the Oscars is so white!”

But it wasn’t Monae’s high-energy performance, featuring Billy Porter, that dropped jaws. That honor was saved for Eminem.

The rapper shocked the crowd at the Dolby Theatre and viewers at home with his performance of “Lose Yourself” — 17 years after it won best original song from the movie “8 Mile.”

The performance came after a montage of iconic songs in film history. While the performance received a standing ovation and cheers from the crowd, many in the audience seemed perplexed as to why the 47-year-old rapper was performing a song released 18 years ago.

He tweeted after the performance, apologizing that it took him so long to get there.
