When 10-year-old Leila Lacase and her mother went to Paul McCartney’s concert on May 17, they brought two handmade signs: one read “Sign my monkey” and the other read “I want to play bass with you.” They took their seats — front row at La Plata Stadium in Buenos Aires, Argentina — and held their signs up, hoping to catch the star’s attention.
When McCartney invited them onstage and offered to sign Lacase’s stuffed monkey, she asked if she could play bass with him instead. Surprised by the question, McCartney asked her if she’d brought her bass with her; Lacase responded by gesturing to the spare bass guitar behind him. “This could be interesting,” McCartney said as a crew member fetched the instrument. “I didn’t see this coming!”
Lacase was handed a white bass that hung to her knees and the band launched into “Get Back,” from the Beatles’ final album, “Let It Be.” An aspiring rock star and lifelong Beatles fan, Lacase played and sang with the 73-year-old McCartney, who graciously lowered the microphone for her.
