The news from Frank Ocean’s Twitter: “SNL this weekend. Me and the bro John Mayer,” which means that Ocean’s set will probably include a snippet of “White,” his Mayer collaboration from Channel Orange. Or maybe he’ll mix it up VMAs-style and have Mayer back him on “Bad Religion.” Or maybe Mayer will bring out his new girlfriend Katy Perry and they’ll all sing “Firework.” Which would you prefer?
