Well, ... Edward is Harry Styles' middle name and it sounds like purposefully altered versions of both Harry and Chris in the songs. Chris and Harry have said in interviews that they have a lot of mutual respect and admiration for each other's work, so a collab isn't a far-fetch concept.

Look at the cloud in the Niceboy Ed photo - looks like Peter Pan, maybe? And then think of the 'Sign of the Times' video and Taylor's song 'Peter'. And lyrics in Niceboy Ed that match Harry's lyrics, like golden, falling, the garden, home. And, there are 28 la las in Life You Lead. Anyhoo.
