Two on a Seesaw

In “All About Me,” which opened on Thursday night, this most dominating of dames is given what feels like less than half a chance. The production also stars Michael Feinstein, the celebrated piano-playing crooner who possesses considerable gifts of his own. But they are of an entirely different stripe from the brasher talents commanded by Dame Edna. Seen side by side, in a production that brings to mind a desperately assembled tv variety show from the 1970s, these six headliners clash like polka dots paired with plaid.

That professionally famous, mauve-haired Australian housewife has returned to Broadway in a show called “All About Me” at Henry Miller’s Theater. But it is not only about her. And, ah, there’s the rub, to use another Edna-ism. Or is that from Shakespeare? Dame Edna has a way of making you believe he invented anything worth quoting — that is, if she’s given half a chance to wrap (and smother) you in her feather-boa-constrictor embrace.

But if you need stars to collide, they had better be in the same universe. Wherever Mr. Feinstein appears, he gives the impression that he is in an intimate supper club from a time when Cole Porter and the Gershwins were the hippest songwriters working. Dame Edna makes you feel that you have been invited in to her own less-than-humble home, palatial to accommodate a self-esteem that turns current trends in to personal trophies.

The appeal of a clash of titans — as in six divas going at it tooth and nail à la “Valley of the Dolls” — is clearly what the producers of “All About Me” were hoping to capitalize on. Early publicity on the show had it that Dame Edna (the fine-tune ego of the courageous comedian Barry Humphries) and Mr. Feinstein were planning separate shows with similar titles. After some public trading of carefully phrased insults, it was announced that the Dame and the singer had agreed to appear together, though strategically leaked reports of skirmishes between them continued to surface.

Mr. Feinstein’s style is silky, glossy and whispery; Dame Edna’s is coarse, loud and harsh. But the most important difference between them is their egos, or how they make use of them. For all I know, Mr. Feinstein’s vanity is as huge and meat-eating as Dame Edna’s. But he presents himself as an eternally romantic boy who labors gratefully in the service of the Great American Songbook.

Dame Edna, on the other hand, labors only in the cause of her own greater glory. To put it bluntly, he belongs in a show called “All About Me,” and Mr. Feinstein does not. Pretending otherwise does neither performer any favors.

There’s a jogging joke about each trying to have the other evicted from the theater, before a brawny stage manger (Jodi Capeless) steps in and insists they play lovely. This involves their being allowed alternating minutes of performance time, until they finally settle in to a couple of duets (written by Mr. Feinstein) about how different yet strangely compatible they are.

The show’s creative team, which includes the director Casey Nicholaw and the writer Christopher Durang, have tried to turn these dissimilarities in to selling points, as if their stars were the new Dean Martin and Jerry Lewis. It’s a he-sings, she-squawks sort of format, with Mr. Feinstein performing Champagne standards like “My Romance” and Dame Edna doing her singular high-heeled stand-up.

Wearing the expected series of resplendently tacky gowns (by Stephen Adnitt), Dame Edna is allowed a few moments to patronize and embarrass audience members as only he can. He gets off a few zingers that linger. And I would seldom trade the memory of having seen Dame Edna crash her way through Beyoncé’s “Single Ladies (Put a Ring on It)” (with the backup dancers Gregory Butler and Jon-Paul Mateo).

But neither star has time to get a groove going that would define the perimeters of a complete, self-contained fantasy world. No matter how radiantly Mr. Feinstein is singing or how amusingly Dame Edna is riffing, you’re aware of the presence of the other, waiting to break in. The show starts to feel like four long, repeated session of coitus interruptus.

More surprisingly, after declaring the theater a “Stephen Sondheim-free zone,” Dame Edna delivers her own version of that composer’s “Ladies Who Lunch,” and it’s terrific. He uses the fear and anger that are part of any comedian’s makeup to turn an overperformed song in to a funny, aggressive and bizarrely affecting acknowledgement of mortality.

I ought to also say that “All About Me” has the wittiest overture in town, a crazy quilt of snippets from a host of Broadway musicals: vamps from “Sweet Charity” and “Cabaret,” a swelling strain from “The Phantom of the Opera,” a glowing passage from “Sunday in the Park With George.” No segment lasts for over a few seconds, so when you’re beginning to settle in to the shape of a familiar melody, it’s pulled out from under you. This turns out be all fitting a preface for the fragmented show that follows.
