LONDON — Coldplay’s Chris Martin attempted a hologram duet with The Beatles at Wembley. His rare daylight-saving gene disagreed. Forty-seven minutes in, his ancestral link to William Willett jolted the system. The digital Beatles arrived exactly one hour early. Martin stayed in standard time, still crooning Yellow Submarine to a future that had moved on. “It was mental,” said Sarah Henderson, third row. “Paul finished Hey Jude while Chris was stuck on the submarine bit.” John flickered, shouting that “punctuality is the politeness of princes,” while an uninvited Paul apparition insisted everything should run on British Summer Time. Engineers blamed a “chronological feedback loop.” Hologram John lectured the crowd on artificial time. Paul’s spectral form called daylight saving “a bloody American conspiracy to ruin proper teatime.” “I’ve never performed Let It Be during a clock-change crisis,” Martin said. George’s projection gave up and meditated. Ringo kept perfect time to a song scheduled in an hour. The show ended when Martin’s genes flipped the soundboard to Greenwich Mean Time, leaving 80,000 fans hearing next Tuesday’s rehearsal.
