On Friday, the official start of the 2012 Summer Olympics in London will be celebrated with an extravagant opening ceremony that will culminate with a performance by Paul McCartney.  Not many details have been confirmed about what the ex-Beatles star will be playing, although media reports from his rehearsals have revealed that one of the songs Sir Paul has been preparing is the Fab Four classic “Hey Jude.”

McCartney discusses his appearance at the big event in a new interview with ShortList.com.  He tells the magazine that playing a special event such as the Olympics “a completely different beast” from performing at one of his own headlining concerts.

“With something like the Olympics, there’s no warm-up, you just come in cold and you’ve got to get up to speed,” he explains.  “It’s like asking an athlete to do his thing without a warm-up: run in, do 100 meters and you’re off.”

Macca also reveals that he and the other Beatles were not particularly good athletes themselves.

“I was the kid who would be in the outfield at cricket and the ball would hardly ever come to me, so I just sort of daydreamed,” he recalls.  “It was the same for all The Beatles, actually.  If there was a big match, we’d kind of watch it…but we never kicked a football around or played a game of cricket on the beach.”

The 2012 Olympics Summer Games’ opening ceremony will air on NBC starting at 7:30 p.m. ET.
