Watch Elton John & Taron Egerton's 'Tiny Dancer' Duet From His Oscars Party

Classic rock played a big part in Sunday night's televised presentation of the Oscars with Queen + Adam Lambert opening the festivities and Bohemian Rhapsody actor Rami Malek taking home the award for Best Actor.

But classic rock was also at the fore at a West Hollywood venue where rock icon Elton John hosted his annual Oscars viewing party as a benefit for the Elton John Aids Foundation Academy.

John performs each year in the party's headlining slot and usually brings out a guest or two to sing with him. This year, that guest was actor Taron Egerton who portrays John himself in the upcoming Rocketman biopic, due this summer.

In a teaser video release last week ahead of the official Rocketman trailer, Egerton was touted by Paramount Pictures for singing all his own parts in the film.

Unlike most music biopic actors who lip sync, Egerton said he wasn't interested in miming John's songs, and John himself reportedly loves the Kingsmen actor's interpretation of his classic songs.

The two even have chemistry together, as they displayed with their duet on John's 1971 hit "Tiny Dancer" at the Oscars party.

Egerton sings the majority of the song by himself before being joined by Sir Elton for the final chorus. Singing an Elton John song to John himself seems impossibly nerve-wracking, but Egerton seemed completely comfortable and sounded great.

Egerton says Rocketman isn't a traditional biopic, but more of a "fantasy musical," in which John's catalog is used to "express important beats in his life at emotional moments."

"Elton's songs are defining moments in people's lives," Egerton said. "And the songs should all come from a place of character."
