What is this Italian song?

Factual Questions
1

This soccer video has an Italian (at least, it sounds strongly like Italian) song as background:

What is this song? Is it famous? Who sings it? Who wrote it?

Thanks for all help!

It’s pretty much the national anthem of Italian soccer. The title is “Un’Estate italiana” (An Italian Summer) composed by Giorgio Moroder and performed by Edoardo Bennato and Gianna Nannini.

For a song manufactured for a sporting event, it’s surprisingly non-terrible. Is it terrible in Italian?

Edit: sorry, maybe “manufactured” is too harsh a term, but that’s how most sports-specific music sounds to me.

Well, Italians know a thing or two about making quality music.
