Who would have thought that a musical as acclaimed as "Hamilton"—Tony Award and Pulitzer Prize among its honors—would not be immune from parody?
Gerard Allesandrini that is who.

The Boston-born, Needham-raised talent—who has his own special Tony for several editions of his "Forbidden Broadway" and wide-ranging comic inventiveness—took on the 2015 Tony-winning phenomenon one year later in a show cleverly entitled "Spamilton: An American Parody."

Now the Boston Conservatory alumnus has brought this alternately funny and thoughtful 80-minute show to the Calderwood Pavilion by way of Huntington Theatre Company in a very sharp revue.

Parody, of course, can be as flattering as pure imitation, and Allesandrini certainly admires writer-performer Lin-Manuel Miranda's terrific accomplishment. After all, Gerry McIntyre's striking choreography captures the taut arm and leg moves of "Hamilton"right from the start as well as the hip-hop and waltz dance work of "Spamilton" 's predecessor.

At the same time, the "Forbidden Broadway" creator has the daring to playfully put upon the musical's often Nascar-speed rap. In fact, many Miranda fans—this critic among them—will agree with Alessandrini's view that his earlier Tony-winning show "In the Heights" is "not very polished."

By contrast, Alessandrini' parody is delightfully polished. The veteran stage humorist smartly gives time to both members of the original Broadway cast and the musical itself. There are particularly funny moments about long-haired Daveed Diggs—brilliantly funky as Jefferson—and Leslie Odom, Jr., a dynamic Tony winner as Hamilton rival and duel killer Aaron Burr.

The funniest take-off on Diggs actually involves an apparent audience member who wanders onstage to ask "What did I miss?"—a reaction that calls to mind Jefferson's question about what is happening in America upon returning from France. For his part, Odom, Jr. declares "You are no Johnny Mercer" and insists on having "My Shot"-the latter recalling the self-empowerment demands that become a "Hamilton"motif.

As always, Alessandrini is wise enough to include pointed, often provocative comments about other shows even if his revue is centered on "Hamilton"" itself. Having one Schuyler sister hold two dummies meant to represent the other Leading ladies makes a hilarious allusion to "Avenue Q" 's mix of humans and puppets.

A number connected to King George III—who humorously underestimates the sentiments and strengths of the colonists—audaciously suggests that Broadway gay talent is giving way to material like Miranda's gay-free musicals thus far. This 'straight' insistence brilliantly plays a reversal on "Spamalot"'s advisory that Jewish input is a necessity for a Broadway success.

A first-rate cast directed by the parodist himself makes this inspired parody a success. Adrian Lope, who resembles Miranda, has the charm and energy to bring to mind the musical's creator himself. Datus Puryear catches the rough resolve of Burr and the intensity of Odom,Jr. Dominic Pecikonis has Diggs' charisma and Jefferson's jazzy demeanor. Ani Djirdjirian captures the three Schuyler sisters with appropriate distinctiveness. Brandon Kinley and Chuckie Benson are equally convincing in a variety of roles.

If you love the various incarnations of "Forbidden Broadway," prepare to be tickled silly by "Spamilton." If you saw "Hamilton" in Boston or New York, you will marvel at Alessandrini's uncanny parody. If you have not, listen to the score and read the valuable liner notes. "Spamilton" is the kind of stage currency that should not be missed.
