You build it. You buy it. This may become the new mantra on Broadway. The original cast of Hamilton was recently followed by the new cast of Disney’s Frozen in receiving a share of the success of the shows they helped create. Similar to a great tech company building towards an IPO, a Broadway company has to do a whole lot of work before it ever gets to the starting line. Beyond the original idea, words and songs are the testing, tweaks, enhancements and embellishments that can make or break a show.
