The article, published by Far Out Magazine, sets out to explain how a "1972 song" reportedly played a part in Leonardo DiCaprio missing out on a role in an Oscar-winning film. Beyond the headline, however, the body of the piece was not included in the text supplied here — what remains is largely the site's navigation and mailing-list prompts — so the specific film, role and song cannot be reliably summarised from the source provided.

As a result, the key details, names and reasoning that the headline promises are absent from the available text. To summarise the story accurately, the full article would need to be accessed directly via the link, as any account of which project, casting decision or track was involved would otherwise be guesswork rather than reporting.
