Sir Elton John took the stage twice at his AIDS Foundation Oscars viewing party in L.A. Sunday night. He accompanied Rocketman star Taron Edgerton on "Tiny Dancer," mostly playing piano, but adding backing vocals later in the song.
He also performed a more tradition duet with Brandon Flowers of The Killers -- who he'd hired to provide the entertainment at the bash -- on "Daniel." You can find his complete performance with Edgerton on YouTube. The Killers posted an excerpt of what he did with them on Instagram.
