The 2015 Brit Awards are going down right now, in London's O2 arena. For those of us who aren't habituated overseas, we've got a live stream of the entire event via YouTube.

Kanye West made a return to the Brit Awards this year after taking a nine-year hiatus from the event, and he made sure his return was memorable by debuting the highly anticipated "All Day" single. The song was initially sidetracked by "Only" and "Wolves," and while it was uncertain if it would see the light of day, those qualms can now be put to rest. He performed it for the first time with a massive posse backing him on stage. 

Check out Kanye's energetic performance below, which included an introduction from wifey Kim Kardashian.

Does the song live up to your expectations?
