Los Angeles: Lin-Manuel Miranda owned Friday's Oscar rehearsals. He sang a tune from 'La La Land', posed like John Travolta in 'Saturday Night Fever', invoked a 1990s Billy Crystal Oscar monologue, and reprimanded his dad from the stage for having his cellphone light on.
The creator of 'Hamilton' joined Sting, Justin Timberlake and John Legend for a day of music rehearsals at Hollywood's Dolby Theatre Friday.
Miranda is nominated for 'How Far I'll Go' from 'Moana'. Timberlake is up for "Can't Stop the Feeling" from "Trolls."
Sting will sing his nominated song from "Jim: The James Foley Story," and Legend will perform the two nominated songs from "La La Land."
Wearing a sweatshirt that read "Rehearsal is the best part," Miranda sang a few bars from "City of Stars" before his rehearsal began.
"I can't get it out of my head!" he said.
Later, he called out his dad from the stage.
"Luis Miranda," the 37-year-old Grammy, Emmy and Tony winner bellowed into the microphone. "Turn your light off. I can see it from here."
