The article text provided is just website navigation/boilerplate ("MusicFilmTravelArtNews Shop Mailing List Cover Story | Yard Act") — the actual body of the piece didn't come through, so there's no real content to summarise. I don't want to invent details about which singers Springsteen supposedly referenced, as that would risk fabricating information.

Could you paste the full article text, or provide a working link I can fetch directly?
