A moment Leila Lacase will never forget

Legendary former Beatle Paul McCartney, 73, spotted 10-year-old Leila Lacase in the audience during his May 17 show at the Argentinian capital's La Plata Stadium. She was holding a sign asking him to sign her teddy bear, so he invited Leila and her mother to the stage. Then Leila revealed the real reason she grabbed his attention. "I want to play the bass with you," she said, as the audience cheered. What happened next she will never forget.

"I didn't see this coming!" McCartney said as a roadie draped a white base guitar over the girl's shoulders. It hung near her feet, but she still plucked along and McCartney lowered the mike so she could add vocals. At the end, he asked the audience, "What did you think of that?" to thunderous applause, and Leila took the mike to say, "Muchas gracias," unfazed by sharing the stage with rock royalty.
