The Weeknd And Ed Sheeran's 'Dark Times' Performance Is Smoother Than Melted Butter

Maybe even smoother.

The Weeknd and Ed Sheeran may be singing about "Dark Times," but it was quite the opposite when the two played the song together on Thursday night.

The Weeknd was performing at his sold-out show in his hometown of Toronto for his The Madness Fall Tour, when Ed surprised the crowd at the Air Canada Centre.

Ed took the stage to a crowd of screaming fans with his acoustic guitar in hand as the two traded verses on the track, which is featured on the Canadian singer's chart-topping album, Beauty Behind The Madness. Their voices were so on point that it felt like you were actually listening to the original song off the album.

"I've written with a lot of people in my life, but he is the fastest and most talented songwriter I've ever worked with, ever..." The Weeknd said on stage after they performed. "I mean, if we stayed in the studio another week, we could've had a full album, maybe."

Umm...that sounds like an AH-mazing idea.

The song actually came together pretty quickly since they wrote it one day after they met, and one night after they partied together.

“When we were at the party, we were really drunk, and he was like, ’You should come to my house tomorrow! We should write a song!’ And in my head, I’m like, the Weeknd doesn’t wanna write a song — the Weeknd doesn’t work with anyone," Ed said back in July. "He’s got one feature on his album, which is Kanye West. He doesn’t wanna do that. And then the next day, he hit me up again, so I went, and we wrote this song, which is really, really f–king good.”
