And musical segments for almost all the other movies you've seen from the '30s onward were prerecorded as well.
As for the dress, the tiered skirt seemed like a reminder of the outfits Diana Ross and The Supremes wore for their first performance on The Ed Sullivan Show. Unfortunately, it was not structured as well as those, as the top tier blew upward several times, revealing that it was made too fast and with too little attention to how it would flow as she moved. And it is time for Diana to ditch all the coats she's worn for the last 40 years and to drop all the black gowns and get back to brighter colors.
Still, it was great seeing her at the top of the bill on this momentous occasion. It's amazing to realize that her career has lasted some 62 years, not that many years less that Elizabeth II's career.
