Elton John hit a milestone last night, when he held his 25th Annual Academy Awards Viewing Party. John’s viewing party isn’t your average party though, as he raises money during the event for his AIDS Foundation. John has raised millions throughout the years.

John hosted his 25th annual Elton John AIDS Foundation Academy Awards Viewing Party last night at West Hollywood Park. Yahoo! Music offers a rundown of the guest list, which included Sting, current Queen singer Adam Lambert and Smokey Robinson, among many others. The event also included a live performance from up-and-coming group St. Paul and the Broken Bones.

John joined the band during their set, coming up on stage for a duet on the song “I’ll Be Your Woman.”

He started off his introduction of the band saying he was  “absolutely delighted to welcome”. John then praised the group “amazing, fantastic musicians” and predicted that the guests would be “thrilled by their performance.” Frontman Paul Janeway obviously came away thrilled — after sharing the mic with John, he told the crowd, “You can’t beat that s—. You can’t beat that.”

Guests had the opportunity to bid on a number of items, including a five-night stay at Steven Tyler‘s Maui vacation home and an invitation to an exclusive party commemorating John’s long songwriting partnership with lyricist Bernie Taupin. This year’s fundraising totals haven’t been announced, but the 2016 event brought in an impressive $6.2 million haul.
