Presented by Motown legend Smokey Robinson, the Aussie quartet, that nation's most successful recording group, delivers a high-energy show that covers a wide variety of R&B classics. Backed by a crack six-piece band, the four do tight harmonies on songs like "I Heard it Through the Grapevine," "Dancing in the Streets," "Stop in the Name of Love," "ABC, 123," and "Uptight" to name a few. The vocals are impeccable, although sometimes a bit in danger of being overwhelmed by the musicians behind them.

That's why the true standout moments are when they go a cappella on songs such as "Just My Imagination" and "People Get Ready." Their harmonies are an intricate blend of street corner doo-wop, barbershop quartet, and boy band white-boy soul and although the band is great, I wish they had taken more breaks than they did.

There is nothing more to the show than the music and the Motown style choreography (and the occasional video clip during costume changes) but the foursome are filled with an almost stereotypical Australian roguish charm that is more than enough to get past the low production values.

The biggest problem with the show is not the show itself but where it is shown. The room at the Imperial Palace is a "classic" Vegas showroom, meaning a few high-backed booths and lots of skinny tables with banquet chairs. To say that it is uncomfortable is a huge understatement and it made me want the show to be over a solid 20 minutes before it actually was.

But if you are a fan of Motown or a fan of music in general, you may want to go ahead and put up with it.
