The article text you provided only contains the page's navigation/header boilerplate (menu links, "Cover Story | Yard Act") — it doesn't include the actual story content about Paul McCartney's Liverpool tour surprise. I also don't have permission to fetch the URL directly to retrieve the full text.

Could you paste the full article body (the actual paragraphs describing what happened), or grant WebFetch permission so I can retrieve it? I don't want to invent details about the event that aren't actually in the source.
