I wasn't able to retrieve the actual article content — the text provided only contains the page's navigation menu and site header (site name, menu links "Music/Film/Travel/Art/News/Shop/Mailing List", and an unrelated "Cover Story | Yard Act" tag), not the body of the piece about halftime shows. There's no substantive text here to summarise.

Could you paste the full article text, or confirm the link so I can try fetching it again?
