This features André 3000 of Outkast rapping the third and fourth verses. Premiering the track on his Beats 1 show OTHERtone on November 10, 2017, Pharrell Williams said that the team effort with 3000 "almost didn't happen."
"There were moments when my stomach dropped out," he noted at the prospect of 3000 contributing to the track. "I knew if 3 Stacks gave us a verse, I knew he was gonna go hard. We just had to talk to him. We're all clear that he's a genius, right? We're all clear that he's an alien? So for him, he has a process, and there's a bunch of things that need to make sense before he even commits himself to something."
David Bowie's "Space Oddity" tells the story of an astronaut who cuts off communication and floats into space. The BBC used it extensively in their coverage of the 1969 moon landing - an odd choice considering the lyrics.
"Cleveland Rocks" was written by an Englishman. Ian Hunter wrote the song after touring America in the late '70s and finding that Cleveland was by far the most receptive city to his brand of Glam Rock.
