The article text supplied for this request does not contain any actual content from the piece — only website navigation elements (menu items such as "Music," "Film," "Travel," "Art," "News," "Shop," "Mailing List") and an unrelated "Cover Story" link to Yard Act. No information about Glenn Frey, the Eagles, or any specific song is present in the text provided.

As a result, I cannot produce an accurate summary of what the article says, since doing so would require inventing details not found in the source material. Please provide the full article text or a working link to it so an accurate, neutral summary can be written.
