I was lucky enough to see the original production, with the original cast, on tour in Los Angeles. I loved it! The book needs a bit of work (and there is a team working on this). In the age of #MeToo there are some cringeworthy lyrics, and I imagine there are some folk who find any show where a woman's goal is to get married beyond the pale today.
Despite the book being a little confusing - its easy enough to untangle. One just needs a fabulous dancer who is a quirky/sexy actress, and fascinating singer to pull it off. Richard Kiley and Leonard Stone were great in the show, as was Ms Verdon, of course.
There are many things not fun about getting older. But having been able to see REDHEAD is one of the things that makes it worthwhile!
