It's kind of a shame that HELLO, DOLLY! didn't come along a few years earlier. I'm sure that David Merrick would have taken Ball as a replacement Dolly for however long she wanted to do it or could commit to do it between seasons of television sitcoms. And that show surely wouldn't have taxed Ball as a singer or dancer as much as WILDCAT might have done. Going in as a replacement for 3-6 months would have been ample time for Ball to discover that she would get bored (if that's the case) or figure out that an 8 performance week was not something she was either capable of or interested in doing.
If FOLLIES had run longer, she might have been an interesting replacement Carlotta had that been something she was interested in at the time.
