The article text provided doesn't actually contain the story — it's just the website's navigation menu ("Music Film Travel Art News Shop Mailing List…" repeated), with no real content about the song, its background, or context. I can't responsibly summarise an article I don't have.

Could you paste the full article text, or confirm the link works so I can try fetching it again? I know from the title alone that this concerns the 50th anniversary of Wings' "Let 'Em In" (1976), but I'd be guessing at the actual details the piece covers rather than summarising it.
