One hour into the Grammy Awards, Beyonce and the ageless, forever sexy Tina Turner are line-dancin' "Proud Mary," in high-spirited, high-steppin' style.
John Fogerty leads the audience in applause, which makes sense -- he wrote the song.
So far, for the 50th Grammy Awards, the emphasis is decidedly on Grammy history, what with Frank Sinatra -- from the grave -- singing with Alicia Keys, a salute to the Beatles via Circque du Soliel and the cast of "Across the Universe," and Tom Hanks handing out a lifetime awards to the Band.
Even the Time stepped in -- albeit with Rihanna doing a medley of hits -- for a bit of "Jungle Love."
Still, Kanye West proved with a formidable "Stronger" -- with glowing glasses and all -- that today's stars have plenty of firepower, too.

Whoa, "Song of the Year" is handed out in the middle of the evening. That's a surprise. Bigger surprise: Amy Winehouse, despite all her troubles, including a stay in rehab" actually wins for "Rehab," beating out multi-format hit "Before He Cheats."
