Paul McCartney hits one out of the park at Fenway concert

BOSTON, July 18 (UPI) -- Paul McCartney hit one out of the park at Fenway over the weekend, performing 39 songs to a packed crowd at the iconic baseball stadium, staying on stage for nearly three hours.

Among the songs he performed were Helter Skelter, And I Love Her, Hard Days Night and I've got a Feeling, with guests including Grateful Dead's Bob Weir and the New England Patriots' Rob Gronkowski.

Gronk, the Patriots tight end, could be seen rocking out on stage with McCartney as the legendary Beatle played Helter Skelter. the Boston Globe reported.

Decked out in a white collared shirt, white sneakers, and blue shorts, the Gronk played some air guitar as McCartney belted out The Beatles' 1968 hit.

McCartney outdid his first performance at Fenway Park when, in 2009, he performed 34 songs, the Boston Herald reported.

In addition to performing iconic Beatles hits, McCartney also hit the Wings catalogue, including Letting Go, then back to The Beatles Eleanor Rigby.

McCartney swapped instruments constantly during the concert, playing bass, acoustic, piano and electric guitar as he performed Band on the Run, Let it Be and Yesterday.

The civil rights tune Blackbird seemed to be timed perfectly for the chaotic times the U.S. has faced in recent weeks. As he prepared to sing it, McCartney noted "Things are not that much better now."
