Prince, Billy Joel and a bomb to Aaron Moorehead

If you've got NFL Network, you can catch Prince's Super Bowl news conference, where he declined to take questions but gave a three-song performance. The place was rocking. I saw several sportswriters slightly tapping their toes to the beat. That's wild, man.

I loved Billy Joel, too. He's singing the national anthem, and took several questions about it, including how difficult it is to sing.

"It’s not the greatest song ever written," Joel said. "What it represents is a terrific thing, but 'America the Beautiful' is actually a better song. It was written in the 19th century vernacular so nobody remembers the lyrics because they don't know what they mean. The melody's difficult, so they drop out on the high notes. It's kind of a slog, actually."

As for the Colts, everyone practiced today except Nick Harper, who's still holding out hope he'll be able to play on Sunday. Dan Marino watched practice. Peyton Manning ended practice with a 23-yard touchdown pass to Aaron Moorehead.

"This is about our 20th week of practice, and I think the defense stopped the offense once or twice all year," coach Tony Dungy said. "When they stop them, we give out game balls."

Dungy was being playful. The Colts are loose, and that should be a good sign.
