Popular singing group Human Nature has ended a three-year run at Imperial Palace (The Quad), performing a final show on Nov. 25, 2012.

The show, “Smokey Robinson Presents Human Nature: The Ultimate Celebration of Motown,” has entertained thousands of Las Vegas visitors since it opened on May 23, 2009. The Nov. 25 show marked the group’s 776th performance at the former IP.

The members of Human Nature are Andrew Tierney, Toby Allen, Michael Tierney and Phil Burton.

A slew of celebs stopped by to see the harmonizing quartet during its stint at the Imperial Palace, including Susan Lucci, Shania Twain (beginning her residency at Caesars Palace on Dec. 1, 2012), Jennifer Love Hewitt and Berry Gordy, among others.

In the near term, the group has tour dates in Florida, followed by a national tour of their native country, Australia.

Some of our memories of Human Nature include their performance on Dancing With the Stars, their appearance at the annual cactus lighting ceremony at Ethel M Chocolates, their memorable photo spread in Las Vegas magazine (see below) and the group’s charitable and community involvement.

No replacement for Human Nature’s show at the Imperial Palace (now known as The Quad) has been officially announced. We wish the guys all the best, and expect the Las Vegas Strip hasn’t seen the last of these exceptionally talented performers.
