“In other words, Berlin conceived shows as events more than as works. As a result, Berlin’s shows do not exactly represent the most enduring oeuvre in the American theater: only Annie Get Your Gun, the show that least obviously addresses its time, has enjoyed an unbroken string of productions that stretches from its premiere to the present. Yet by engaging with the here-and-now, with no apparent thought of posterity but mainly of the “mob” before him, Berlin distilled and packaged musical comedy conventions that resonated in the theater deep into the twentieth century even as they held to comedy’s ancient ideals. Above all—and this I think manifests the engine that drives all of his work—Berlin seems to have understood and embraced the idea that American musical theater is always, inescapably, about itself. He probably would have scorned the term metatheater, but the boot fits. All of his stage shows and films are in some way about theater, about putting on a show, about performing in public, and about the place that tested his mettle and nourished his craft: New York City. This is the case even in shows that are not chiefly set in New York. Annie Get Your Gun may be widely considered one of the “Western” musicals of the Oklahoma! age, but it is above all a show about “show business,” and it all takes place east of (or near to) the Mississippi River and ends up in New York, with plenty of swinging tunes that resonate more with postwar Manhattan than with Annie Oakley’s earlier America in Darke County,”

“As Duke Ellington put it, Henderson "was liberal in giving away his ideas to people. So liberal, in fact, that it is difficult to recognize the original Fletcher Henderson through his flock of imitators.”
