Next year will mark the thirtieth anniversary of Disney’s attempt to revive the musical. Before the “Hamilton” craze and “The Greatest Showman”, musicals had hit a slump. Except for shows like the stalworth “Annie”, the musical was seen as a fossil best left in our memories of the greats like Gene Kelly and Fred Astaire. Then along comes “Newsies”, a historical musical about the New York paperboys of 1899 in their campaign to fight back against the major newspapers who were trying to put the squeeze on them.
