^^^ Fair enough. What's most amazing to me so far (and what I didn't completely get from the series) is that Verdon was ultimately the costumer for the film of CABARET!
Per the book, the Germans were so anxious to bury their Nazi past, they banished all real artifacts from the Nazi period to backrooms. What the credited German designer gave Fosse were all fakes, not really the clothes of 1930s Germany, and Fosse found them unusable.
Verdon costumed the movie by combing through thrift stores all over Germany to find authentic pre-war apparel. The colorful kimono that Minnelli wears in the film came from Verdon's own closet.

I remain astonished that so many people found the scene "overwrought" where Verdon's 11 o'clock number became a duet. I don't think those posters understand what a big deal that must have been! Perhaps they should consider that Verdon's introduction to the material was a non-musical film version of the source play. The film was called Roxie Hart, not Roxie and Velma. In fact, if I am reading Wikipedia correctly, Velma is a minor character in the movie; Velma in the musical seems a composite of several female characters in the film.
Again, Chicago was to be Verdon's comeback and, likely, swan song. Rivera was eight years younger and already doing the heavy lifting in the show's dances. Rivera already had the opening number as a solo and was a much stronger singer than Verdon. Verdon had to have known that "All That Jazz" was a bigger solo than her own first number, "That Funny Hubby of Mine". Bigger, really, than any of Verdon's solos, with the possible exception of "Roxie".
Had Verdon done "Nowadays" as a solo, it would have gone a long way to reminding the audience that SHE was the headliner. Of course, Fosse was right to make the change; but Verdon had just sung the number for those assembled and it had been written for her. She was delighted and expected others to share that delight.
If anything, her reaction in the TV show was subdued, IMHO.
