Steve&Eydie.

That might look like a typo, but it's not. Two people, sure, but forever linked and perceived as a single unit.

Steve Lawrence and Eydie Gorme are, of course, one of show business's most durable married couples and a consistently popular act - they've been performing side by side since 1960.

Steve&Eydie hit the Cerritos Center on Saturday night as part of their "One More For The Road" tour. ("If we do good here," Lawrence joked with a big smile, "it could mean Artesia!") They're not retiring, not by a long shot, but definitely scaling back on live shows. Two hours and 10 minutes later, the ecstatic, sold-out crowd had been treated to a delightful lesson in why this duo has been on top for so long.

What do they offer? Not much: merely a huge dose of good, old-fashioned showmanship, heaping bites of glitz and pizazz, large nuggets of Vegas- style humor and a general sense of loving camaraderie and good spirit.

Oh, and they can also sing.

Whether belting out duets or performing stints alone, both of these artists possess big, Broadway-style voices that are none at all the worse for all the wear. And they are perfect for straightforward, emotive interpretations of Gershwin and other contributors to the Great American Songbook.

Lawrence was just as effective on ballads ("Portrait of My Love") and dramatic show stoppers ("I've Gotta Be Me.") Gorme's solo shots included a nattily burlesque-ish "After You've Gone" and even a pretty tune from one of her trailblazing (and largely unheralded) Spanish-language albums.

Duets? It's hard to imagine a pair doing more justice to "Baby It's Cold Outside" than Steve&Eydie did Saturday night. And their long, elaborate, shotgun-style Frank Sinatra medley was nearly worth the price of admission in itself. The big, Vincent Falcone-conducted orchestra was fine throughout.

And the shtick. Loyal fans have heard some of the jokes before, no doubt, but the mostly gray-beard crowd was brought to laughing tears anyway. Much of the self-effacing humor deals, of course, with getting older and the strains of such a long marriage. ("I took Viagra, and all I got was a stiff neck," Lawrence says.) And lawyer jokes. And Michael Jackson and Dennis Rodman jokes. Lawrence capped it all with a sprightly rendition of Robert Klein's hilarious "Colonoscopy": "It opened up a whole new world to me and I saw it all on TV."

The show began with a moving retrospective on a big screen behind the stage, and it provided a vivid reminder that Steve&Eydie were indeed the icons of a fast-fading generation. So many of their cohorts are gone - there they were in living color with Judy and Sammy and Frank and Steve Allen and Lucy. And so many more.

Will there be room for this kind of entertainment in the world again? Probably not. And that's a bad thing. Bad and sad.
