Imagine all the people being asked to step on stage to rock out with the legendary Paul McCartney? Pretty epic right, and that’s exactly what happened to a 10-year-old lass in Buenos Aires, Argentina.

Leila Lacase was holding up a sign during Paul’s concert when the former Beatle spotted her. The rest is rock ‘n roll history, with the peeps over at Rolling Stone covering it:

“I didn’t see this coming!” McCartney said as a roadie draped a white bass guitar over the girl’s shoulders…The instrument dangled near Lacase’s feet, but she still plucked along with the Beatle who lowered the mic so she could add vocals.

“What did you think of that?” the singer asked, triggering thunderous applause. “Muchas gracias,” Lacase said into the microphone, unfazed by sharing the stage with rock royalty.

Ag lekker man – here is the video of the two rocking out:
