BWAY Baby2, this is the second time in this thread you have taken a minor point in a post of mine and gone off on it. Maybe that's a habit that doesn't need to be encouraged, but no harm done.
It was a different era--a year later I walked up to the b.o. and got a last-minute ticket to the newly opened ANNIE--and Minnelli's appearance in CHICAGO wasn't advertised. You seem to imply you saw it at a Saturday matinee. How would the matinee ladies even know about it (at least before the Times re-review)?
In the TV series, which is not always factually accurate of course, Fosse tells Verdon there was an unusually long line at the box office as soon as Minnelli began appearing in the show. As I said, I lived over a thousand miles away, so I was merely reporting what friends in the business told me about the reaction to Minnelli's appearance. And what theater people were saying is more germane to Verdon's feelings than whether you got tickets to a matinee.
And while I'm on the subject, it was also clearly implied in the TV show that Fosse wanted to see his show with a younger star (Minnelli was 30; Verdon was 50) and that, as much as anything, must have been a blow to Miss Verdon. Like all dancers and like the series shows (ad infinitum), she had to be painfully aware of the short shelf-life of a dancer's career. (It may not have been just their personal relationship that led Fosse to follow Verdon with Ann Reinking, age 28 or 29.)
As I'm sure you recall, the really hard-to-get ticket that year was A CHORUS LINE. But on the whole, the 1970s was New York City's and Broadway's financial nadir, with the city gaining a reputation for being filthy, crime-ridden and in disrepair. Tourists were not flocking to Broadway as they had in the 1960s or as they do today. So you got your tickets. I envy you, I really do!
