"I don’twhy you people are convinced that the show cannot run without a star. Did Jersey Boys have a star? Not really, and yet it was appealing to essentially the same demographic."
I like your optimism and I don't want to take that away from you, but I do want to emphasize some key details that differentiate Jersey Boys from Just In Time.
Jersey Boys premiered on Broadway with a cast of complete unknowns. Its star was a nobody making a Broadway debut; I could be wrong, but I don't think a single member of that cast had starred in a Broadway musical prior to Jersey Boys. Certainly not any of the guys playing the Four Seasons. The show was marketed on the strength of the story and the nostalgia of the music, NOT the recognizability of the star. That's why it was so easy to continue replacing the lead roles with unknown actors (many of whom would later become bigger stars, like Andy Karl and Andrew Rannells!)
On the other hand, Just In Time has ALWAYS been a star vehicle whose marketing has ALWAYS revolved around the name recognition of its star. Just look at how big Jonathan Groff's, Matthew Morrison's, and Jeremy Jordan's names and images are on almost every poster, Playbill, etc. I mean, normally if a Broadway show has a gap between a star leaving and a new star coming in, an understudy or alternate will play the role for 2-3 weeks in the interim. However, as we see with Just In Time, they bring in another major star to fill that gap.
Stars were born with Jersey Boys. Existing stars are plucked from the heavens and put on stage for Just In Time.
That being said, whilst on the Jersey Boys train, I'll still echo what others have said on this site, which is that it would be so cool if John Lloyd Young played Bobby on the tour.
