Macca keeps his kit on

Super Bowl chiefs decided to put the entertainment for one of the world's biggest sporting events in the safe hands of Sir Paul McCartney - and they were proved right when the only garment he removed was his jacket.

Janet Jackson caused uproar at the US football final last year when she exposed a nipple, which was later described as "wardrobe malfunction". It resulted in numerous complaints, grovelling apologies and a £300,000 fine for TV broadcaster CBS.

The 62-year-old former Beatle played some old favourites for just 12 minutes - and earned himself £1.8 million or £2,500 a second.

Sir Paul joked that there would be no repeat of last year's performance. "I don't have a wardrobe to malfunction," he said to the crowd. "I can safely tell you I won't strip because you don't want to see me naked. "

The game between the Philadelphia Eagles and victors the New England Patriots was screened to 90 million TV viewers

in the US and one billion around the world. Performers before the game at the Alltel Stadium in Jacksonville, Florida, included country singer Gretchen Wilson, Alicia Keys and Black Eyed Peas.
