With celebrity guests from Adele to Lin-Manuel Miranda, James Corden's "Carpool Karaoke" has blown up this past year.
But most people don't know that the segment dates back much earlier than this year: it actually got its start in 2011, with none other than George Michael.
In June, Corden spoke about the beginnings of Carpool Karaoke on Howard Stern's SiriusXM radio show.
Corden said that first clip with George Michael paved the way for the now-popular segment.
"We couldn't put our finger on why is this so joyful? There's a joy in here. We couldn't really work out why," Corden said.
Following news of Michael's death, Corden paid tribute to the star on Twitter:
"I've loved George Michael for as long as I can remember. He was an absolute inspiration," he said. "Always ahead of his time."
