The "correct style" for what?
Certainly not a disco hit in the '70s. Beyonce's version nails that completely... and the previous versions I've heard, including the OBCR have NOT. That was one my biggest head-scratchers with the original show when I saw it. How could they promote that fluffy "nerdy" sound as the "new dance music" (meaning disco)? It was a misfired arrangement. They have (happily) corrected that for the film.
And I never "bought" Audra's "Deena" as a hugely successful '60s-'70s pop diva for one second. I don't care how well she acted the part, her "legit" voice training came through on every note and was ill-suited for the Dreams material.
