I want to know the answer to the following question:
Where did Kanye perform his single "All Day" with a menagerie of other artists?
All the background I'm provided with is that "West performed the song at the 2015 BRIT Awards with a number of US rappers and UK grime MC's including: Skepta, Wiley, Novelist, Fekky, Krept & Konan, Stormzy, Allan Kingdom, Theophilus London and Vic Mensa.". Is that enough to answer the question?
