MOSCOW — Newly declassified KGB files claim The Beatles’ “Yellow Submarine” covered up an actual heist. In 1966, a lost Ringo Starr allegedly commandeered a Soviet K-class sub at Murmansk, asked where the “yellow one” was, then painted a gray vessel himself. The sub, K-127, later appeared in Liverpool with a note: “Sorry lads, needed a lift home. —R.S.” Vladimir Putin now demands the sub’s return and $47.3 million in docking fees. “This submarine belongs to the Russian people,” he said beside a photo of the bright vessel. “Mr. Starr enjoyed his little joyride; now he faces consequences.” Russia will accept rubles, crypto, or “an autographed copy of every Beatles album, including the bootlegs.” A Cambridge maritime-law expert cites photos of Ringo at the controls and a radio voice asking, “How do you make this thing go backward, mate?” Starr, 85, denies any “submarine-related activities.” Musicologists are reexamining “Octopus’s Garden.” Liverpool Harbor reports a “suspiciously bright yellow object” surfacing at high tide. Putin’s deadline: month’s end—or Russia will seek “all yellow objects in British possession.”
