They're all grown up, and they've still got it. Saturday night at Showcase Live, Grammy-winning group Boyz II Men reminded a sold-out audience why they're one of the most successful boy bands - if you can call them that - in R & B history.

With bass Michael McCary's departure due to health issues, the one-time foursome has been reduced to three members: Nathan Morris, Wanya Morris and Shawn Stockman.

Even as a trio the full-grown crooners put on a polished, spirited show that set the venue ablaze from the opening sounds of "Motownphilly," the ubiquitous new jack swing hit that resurfaced during the encore to close out the nearly 90-minute set.

Though the band tried to work in some more recent material, the crowd was most receptive to hits from the group's early-to-mid-'90s heyday, including power ballads "On Bended Knee" and "End of the Road," the cascading harmonies of "Four Seasons of Loneliness" and the ultra-smooth "Water Runs Dry."

Dressed in three-piece suits and sunglasses, the men remain classy as well as talented. On the well-timed "A Song for Mama," Wanya Morris belted out lyrics into his phone - presumably to his mother - and encouraged members of the audience to dial up their moms and do the same. The bedroom-ready "I'll Make Love to You" elicited shrieks as the trio doled out red roses to swooning fans.

The 18-year music vets - originally signed to Motown Records and heavily influenced by the Motown sound - also included a popular Motown segment with songs pulled from their 2007 album "Motown: A Journey Through Hitsville USA."

Among those classic hits were "The Tracks of My Tears" by Smokey Robinson and The Miracles, The Temptations' "Just My Imagination" and The Four Tops' "It's the Same Old Song," complete with choreography.

There was no live band on Saturday, just pre-recorded backing tracks, the group's expert harmonies and alternating turns on lead vocals, though Wanya Morris, already sweating by the third song in, remains a standout in that department. His a cappella version of "It's So Hard To Say Goodbye To Yesterday" during the encore probably caused more than a few eyes in the house to mist up.

Though the group has faded in popularity - at least in terms of records sales and chart positions - the show was hardly an example of one-time musical juggernauts searching for their stuff. Their live performance may feel like a trip down memory lane or a time warp back to a bygone R & B era, but even today Boyz II Men are still in the groove.

Boston-based girl group Jada - a pop/R & B act signed to Universal Motown records - held down opening duty, including their single "American Cowboy" as well as a cover of En Vogue's "Hold On (Who's Loving You)" among a handful of songs.
