Have picked up the vibe in late spring that once mask and vax requirements lapsed, and NYC moved away from dire infection and hospitalization rates, Broadway would return to a replica of its pre-Covid self. Anecdotal evidence suggests otherwise. Many of us can provide accounts from our personal lives of friends and family becoming infected or re-infected. And with both stars of Music Man re-infected, plus Feldstein -- and 7 outs in one performance of Chicago last week, it's fair to presume the era of the heroic cover is here to stay.
What that does to box office and advance sales, at least for shows with bankable stars, remains to be seen. But there's nothing in the scientific projections that suggest Covid infection rates will necessarily fall beyond flattening, only that -- knock wood -- serious illness is less threatening. Arguably, as per other posts, making theaters less safe from infection won't inspire hoards to return. I still know many who haven't gone back, or who only went once or twice vs ten-fifteen times in prior seasons.
