The coolest dad in music (voted in this new survey) and let's just face it -- one of the coolest cats around -- turns 71 on Tuesday (June 18).

Fresh off his headlining performance at Bonnaroo in Manchester, Tenn., Paul McCartney has a couple of days off before resuming his "Out There" tour Saturday in Warsaw, Poland. The outing will wind down in August.

And after all of these years, McCartney admits he still gets some jitters before taking the stage. "I still get a little excited, a little nervous but I just push it to one side," he said in a short video from this month's two sold-out shows at Barclays Center in Brooklyn, N.Y. "I say, 'Paul, these people are your friends. They love you and you love them. So go and sing, do your best and have a great show.' And I say, 'Thank you conscience.' And that's how we do it."

He continues to do just that night after night in 2013, as the former Beatle shows no signs of slowing down any time soon. He performed nearly three hours at Bonnaroo last weekend, and has been introducing different material into his set, including "Eight Days a Week," a classic that he played for the first time live on the current tour.

It's been 46 years since McCartney and the Beatles gave us the song, "When I'm Sixty-Four," with McCartney singing: "Will you still need me, will you still feed me, when I'm sixty-four?"

Now long past the age of 64, the answer to that question McCartney, is "yes." You have proven that the music world definitely still needs you. Keep rockin' Sir Paul, and happy birthday!
