Kanye West debuted his much-leaked single “All Day” at the Brit Awards last week, and now a studio version has emerged. The So Help Me God song’s bouncy, bass-heavy beat also features verses from Allan Kingdom and Theophilus London, and a massive “Monster”/”Black Skinhead”-style riff slices through the track from time to time. There’s also an interlude with just whistling and acoustic guitar, which was certainly not expected! Hear the officially official, finally final version at DirectLyrics.

So Help Me God could be coming any time.

UPDATE:

Such an honor to be on a song with Paul ! What a legend . Paul McCartney ????

Paul McCartney is the one whistling on “All Day.” It appears to be a sample from the end of his unreleased obscurity “When The Wind Is Blowing,” from 1970.

Here’s the full list of composers on the track: Kanye West, Paul McCartney, Tyler Bryant, Kendrick Lamar, Karim Kharbouch, Cydel Young, Victor Mensah, Mike Dean, Che Pope, Noah Goldstein, Allen Ritter, Mario Winans, Charles Njapa, Malik Yusef Jones, Patrick Reynolds, Ernest Brown & Noel Ellis.
