And another step forward in the destruction of musical comedy.
First of all, when the term "musical comedy" was used in the 1980's stage version of 42nd Street, it already felt like a nostalgic, almost pastiche term. Did you mean "musical theatre?"
Second of all, I was around 11 or 12 when I first started paying attention to Broadway shows. I'm 58 now. For all of those years I've been hearing that the musical (and musical theatre in general) was dying, or dead, or being destroyed, etc. And yet, here we are, even after a major pandemic that closed everything down, still with new musicals being written and yes, celebrated. I'm not sure whether to strike up a chorus of "I Ain't Down Yet" or "He Is Not Dead Yet" or even "And I Am Telling You (I'm Not Going)," but your "destruction" comment just doesn't ring true.
BTW - I'm not a huge fan of jukebox musicals either. But that doesn't mean that anything is being "destroyed" by having them.
