Sir Paul McCartney reportedly left streetcar riders in New Orleans amazed on a recent ride.

The 70-year-old musician and his wife Nancy Shevell were in Louisiana celebrating America’s Super Bowl sporting event.

While in the city, apparently Paul was happy to take public transportation.

The star even decided to give his vocal chords a stretch while journeying to his next destination.

“This guy got on the street car and started singing Beatles songs,” local resident Robert Senft told British newspaper The Mirror.

"Everyone was just ignoring him because there’s a lot of buskers in this town.

“He started to sing directly to my friend Evelyn. We realised it was Sir Paul McCartney and were in shock.”

The event was momentous for another key reason.

For a few minutes the entire streetcar was in musical harmony.

“He started singing with the whole carriage and taking pictures,” Robert explained.

“It was a once in a lifetime experience.”

Beyoncé Knowles performed with fireworks in the background and giant screens showing versions of herself dancing to her tracks in front of the 70,000 strong crowd at the Super Bowl on Sunday. She also reunited with her former group Destiny’s Child while onstage.

Alicia Keys and Jennifer Hudson kicked off the game that attracts an average annual audience of over 110 million.

At the Super Bowl, Baltimore Ravens were eventually triumphant over the San Francisco 49ers.
