It is obvious in this case that the information is wrong, but what of the many songs that Google misleads people into thinking are likewise locked up in rights? It's simply ridiculous on the face of it.
Edit: Getting into the weeds a bit here, but I don't think performances themselves can be copyrighted (in the US, that is). Recordings can be copyrighted, as can musical compositions, lyrics, and subsequent arrangements. It is my understanding that, in order for something to be eligible for copyright, it must be fixed in a "tangible medium of expression."
It's also worth mentioning that music publishing companies generally control compositions, not recordings. But even supposing Concord Music Publishing has copyright on the arrangement used on that particular occasion, that does not imply they have copyright on the lyrics.
While other aspects of the Super Bowl arrangement and performance are under copyright, the lyrics aren't.
