The Sunset Strip had a Wonderful Crazy Saturday afternoon. To thank West Hollywood for hosting his Academy Awards viewing party and welcoming his AIDS Foundation, Elton John performed a free pop-up concert featuring a duet with Lady Gaga.
Mother Monster joined John on stage to perform “Don’t Let the Sun Go Down on Me.” Following the performance, Gaga said, “Give it up for this wonderful man, who’s inspired people for generations. Wonderful Crazy Night [John’s latest album] is a beautiful record, and thank you so much for the Elton John AIDS Foundation. We all appreciate it so much.”
In a statement before the concert, John said of the city, “We are profoundly grateful for their generous support, so I wanted to do something special just for them by giving our West Hollywood fans and supporters a surprise concert.”
“This great man has inspired generations with his powerful music and warm heart there will never be another like him and there never was before,” Gaga continued in a post on Instagram. “His uniqueness is compounded by his ability to love endlessly while also creating the biggest hits the world has ever known.”
Gaga and John performed together during the Muppets‘ Thanksgiving special in 2013, in addition to the 2010 Grammys. Gaga will next perform her Oscar-nominated song “Til It Happens to You” during Sunday’s Academy Awards ceremony.
