JACKSONVILLE, Florida -- It's the most important guarantee since Joe Namath in Super Bowl III.

"No worries,'' said Sir Paul McCartney. "I can safely tell you I won't have a wardrobe malfunction. I'll be naked!''

OK. He was kidding about the last part.

"I don't have a wardrobe to malfunction.''

McCartney, 62, will be the only performer during the NFL's 12-minute halftime extravaganza on Sunday. He promises not to cause the same furor Janet Jackson stirred up last season when Justin Timberlake tore open her top at the end of the show and revealed her bare breast - the infamous "wardrobe malfunction."

After last year's infamous Nipplegate affair, attendance at yesterday's halftime show press conference was more or less mandatory.

Jackson's right breast received more coverage after the "uncoverage'' than Patriots quarterback Tom Brady's right arm or teammate Adam Vinatieri's right foot.

"To tell you the truth, I didn't see last year,'' said the legendary Beatle, who will be making his second Super Bowl appearance. In 2002, the first Super Bowl after 9-11, McCartney performed the song Freedom in New Orleans.

"That was a special one. I just came on to do that one, to give that message to America.''

This time he's here as kind of a make good to America after Jackson's boob job last year.

McCartney even admitted it as he played the main interview room, absolutely jammed with reporters, cameras and other secondary celebrities, such as Paula Abdul.

One question from the floor was wonderfully phrased. McCartney was asked how he felt when he came to Jacksonville 40 years ago representing "the moral decay,'' and how he was coming back representing, "the restoration of family values.''

McCartney laughed.

"I had a slight inkling there might be something like that to it,'' he said, of the NFL needing somebody to make up for what happened.

He said he has not been told what to sing.

"When they asked me to do it, I asked them how long. Then I told them what I wanted to do and they said, 'OK.' I'm going to use the time to just rock. I think the crowd will like it. We'll have fun.''

One media type asked him if he'd thought about the songs he was going to play.

"I hope so,'' he said.

Another asked him what band he was going to use.

"My band. I have a band. I call it my band.''

Before McCartney entered the room, the media was informed that no personal questions would be taken and that all questions should be related to the Super Bowl.

So somebody asked him about football.

"I like American football,'' he said. "Our game is what you call soccer. At first I couldn't get the game.

"I couldn't figure out what they were doing. Then somebody told me to watch the guy in the middle,'' he said, "the quarterback."

He had only one prediction for the game in this city, which has seen nothing but cold and rain since the teams arrived here Sunday.

"It will not rain. It will not. I know these things.''

McCartney played here with the Beatles after a hurricane hit the area. He said he remembered the performance because of that.

"This is a big one,'' he said of the 240 seconds or so that he'll perform.

While Jacksonville is getting slaughtered in the media as a Super Bowl host, McCartney said he thinks Jacksonville is going to come out a winner in all this.

"After Sunday, I'm sure Jacksonville will pull it off.''
