Lady Gaga’s collaboration with Beyoncé has nothing on her Sunday night duet. Yoko Ono lay atop a grand piano with the “Telephone” singer by her side at Los Angeles’ Orpheum Theatre at the second of two performances from the Plastic Ono Band—the supergroup John Lennon founded in 1969. “For the first time in an evening of poignant, strange and thrilling star turns, Ono seemed slightly disarmed and tickled—like at last she’d again found a collaborator equally capable of making mischief and merry,” according to the Los Angeles Times. When the performance came to a close, the two reportedly lay in each other’s arms and embraced in “a pose not unlike that snapped by Annie Leibovitz 30 years ago, when a naked John Lennon cuddled his wife, Ono,” the paper reported. The nearly three-hour show also included actor Vincent Gallo, Sonic Youth rockers Kim Gordon and Thurston Moore, and rapper RZA. Sean Lennon took over his dad’s role as the band’s musical director. The celebratory performances occurred on the eve of what would have been Lennon’s 70th Birthday, and the Gaga-Ono moment was the unequivocal highlight of the evening. “Thanks for being so brilliant and such an inspiration to so many women,” said the 24-year-old pop star as she saluted the 77-year-old feminist pioneer.
