The evening event, which was held at Red Studios, honored Elton’s fabulous career with Rob Lowe taking on host duties. Like an awards ceremony, Elton’s birthday featured musical performances by Lady Gaga, Ryan Adams, Rosanne Cash and Stevie Wonder. Gaga, who is godmother to the birthday-boy's two sons, and Stevie, notably joined forces to perform Stevie's 1980 hit Happy Birthday. Stevie also sang Elton's 1973 song Daniel, while Lady Gaga also performed her 2011 single Born This Way for the crowd.

Prince Harry made a memorable cameo at the event, appearing in video-form to wish the singer a happy day. The royal emulated one of Elton’s signature looks, wearing 70s style star-shaped sunglasses. E! News reported that he was also seen pretending to read from the July 2016 issue of UK's gay magazine Attitude, which featured him and his brother Prince William on the cover. The royals have remained close to Elton, who was good friends with Harry and William’s mother Princess Diana. Elton was heartbroken after her 1997 death, honoring her with a personalized remake of his hit song Candle in the Wind.

Elton’s 50-year writing partnership with Bernie Taupin was also spotlighted at the gala, which benefited both the Elton John AIDS Foundation and the Hammer Museum at UCLA. Ahead of the event, Elton spoke with Beats 1’s Zane Lowe, saying, “Some people don’t like birthdays, they don’t like celebrating, they don’t want to know about them, and I’ve always enjoyed my birthday… Seventy sounds so archaic, doesn’t it? When I was growing up, 70 sounded like the end of the world. But things have changed — you’re only as old as you feel inside.”
