How wonderful life is while Sir Elton John's in the world ... for 70 years, as of Saturday!

The singer, pianist, composer and icon celebrated his 70th birthday at Red Studios in Los Angeles over the weekend. But this wasn't just any old birthday party — it was a celebration of a 50-year songwriting partnership with Bernie Taupin, and a fundraiser benefiting the Elton John AIDS Foundation and the Hammer Museum at UCLA.

Plenty of famous friends attended, including Lady Gaga and Stevie Wonder, who joined forces to deliver the ultimate birthday serenade. Melanie Bromley, Chief News Correspondent for E! News, captured the moment and posted the epic video to Instagram.

Ryan Adams and Rosanne Cash also performed, while actor Rob Lowe hosted the event.

But first, there was a red carpet. Well, a tan carpet. A red one would have clashed with Sir Elton's signature suit-and-sunglasses ensemble.

John recently told Beats 1's Zane Lowe, “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?” he continued. “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.”

Sounds like words to live (and live and live) by! And with a new "Devil Wears Prada" musical in the works, it seems like John is keeping plenty busy.

Happy birthday, Sir Elton!
