John Lennon married pregnant Cynthia Powell at Liverpool’s Mount Pleasant Registry Office. Brian Epstein was best man and paid for the luncheon; Paul McCartney, George Harrison, Cynthia’s half-brother Tony Powell, and others attended, while John’s Aunt Mimi boycotted the ceremony. Lennon spent the wedding night playing a Beatles show at the nearby Riverpark Ballroom.

The Beatles released “She Loves You” in Britain, backed by “I’ll Get You.” It spent 31 consecutive weeks on the U.K. chart, 18 in the Top Three, and sold 1.93 million copies—then a record for Britain’s best-selling single.

The Beatles played Shea Stadium for the second time with The Remains, Bobby Hebb, The Cyrkle, and The Ronettes as support. They performed 11 songs for $189,000, though 11,000 of the 55,600 tickets remained unsold.

The Beatles worked on “Your Mother Should Know” at London’s Chappell Recording Studios, adding backing vocals for the “Magical Mystery Tour” project. It was the last studio visit from manager Brian Epstein, who died four days later.

The Jimi Hendrix Experience, Soft Machine, and Big Brother and the Holding Company appeared at the New York Rock Festival in Flushing Meadows under heavy police presence after an earlier chair-throwing riot at the venue.

The Rolling Stones’ “Honky Tonk Women” became their fifth U.S. chart-topper and also reached No. 1 in Britain. It was the last Stones hit to include original guitarist Brian Jones, who had died the previous month.

Emerson, Lake and Palmer made their debut at Plymouth Guild Hall. The successful show was their only warm-up before the Isle of Wight Festival six days later; the trio would eventually sell more than 40 million records and place 10 albums on each the U.S. and U.K. charts.

The Beach Boys became the first rock band to appear on the cover of People magazine. The bearded original members were pictured under the caption “Still Riding the Crest, 15 Hairy Years Later.”

David Bowie’s “Ashes to Ashes” topped the U.K. singles chart for two weeks, his first British No. 1 since “Space Oddity” in 1975 and, at the time, his fastest-selling single.

Oasis’s “Be Here Now” sold 695,761 copies in its first three days in Britain, setting a record as the fastest-selling album ever. It reached No. 1 in the U.K. and No. 2 in the U.S.

Queen became the first rock band to receive official approval in Iran, where Western music was heavily restricted. Freddie Mercury, who died of AIDS in 1991, had Iranian ancestry, and Queen albums had long circulated there as bootlegs.

Queen guitarist Brian May earned his doctorate in astronomy 36 years after beginning his thesis. He had left his studies for music, then completed a 48,000-word dissertation and defended it in a three-hour examination.

Linda Ronstadt revealed that Parkinson’s disease had left her unable to sing. She also needed walking poles on uneven ground and sometimes used a wheelchair.

NASA named a golf-ball-sized Martian rock after The Rolling Stones. The pebble had rolled about three feet when the InSight spacecraft landed, prompting Mick Jagger to joke about putting it on the band’s mantelpiece.
