The provided article text does not contain the actual news content — it only includes the page title and website navigation elements (menu items such as "Music," "Film," "Travel," "Art," "News," "Shop," and "Mailing List"), with no substantive information about what Dolly Parton said or who she referred to as her "musical sister."

As a result, there are no factual details, quotes, or context available to summarise. Retrieving the full article text directly from the source would be necessary to provide an accurate summary.
