If Michael Clift was going to create a show that paid tribute to the Brothers Gibb, it had to be great if it was worth doing at all. Mention of the Bee Gees brings to mind the heady days of disco for many, and a production titled The Australian Bee Gees Show—A Tribute to the Bee Gees is sure to draw people who welcome an onset of night fever and want to get up and dance. It had little trouble filling up a showroom at the Excalibur five nights a week when Clift and company brought it to Las Vegas in February 2011—but they had a few years to hone it before hitting the Strip.

“I started the show 20 years ago in Northern Australia,” says Clift, unmistakably Barry Gibb onstage with his beard and shoulder-length hair, after a Thursday night performance. “Wayne (Hosking), who was playing Maurice tonight, and Dave (Scott), who was not here and plays Robin, they were the original members. Tony (Richards, bass) joined not long after that.”

New Zealander Rick Powell joined on drums after The Australian Bee Gees Show opened in Vegas, and with the addition of alternate cast members such as tonight’s Robin—Paul Lines—The Australian Bee Gees Show has been able to deliver more than 1,700 performances with little more than three video screens to augment the presentation.

Even those aren’t really necessary, but they help create separation between the two main musical eras of the Bee Gees (Maurice Gibb died in 2003, Robin in 2012). After kicking things off with “Nights on Broadway,” “Jive Talkin’” and “More Than a Woman,” the band delivers a British Invasion-era selection of songs including “I Started a Joke” and “Massachusetts” that makes sing-alongs irresistible to many in the audience.

A video homage to early ’70s live music—the fictional “Midnight Sessions”—gives the “brothers” a chance to change from ’60s fashions into Saturday Night Fever styles, and the audience to hit the dance floor near the stage.

“We thought of the concept first, and then we thought of how we were going to do it,” says Clift. Hosking, Clift and Scott were working on projects together Down Under, but Clift slipped into the role of Barry pretty easily, and Scott’s resemblance to Robin meant his lead guitar skills would take a back seat to his lead vocalist ability. Hosking donned a hat and wore a beard as Maurice did, and the Australian musicians set about becoming Bee Gees.

The production’s Maurice also became the comic foil of Barry and Robin. He’s the one that slyly flatters each night’s audience by telling them they sang better than the previous night’s crowd, and he’s the one who gets blocked from the mic by Robin when his vocals are not required. But it’s the irresistible energy of the Bee Gees’ music that makes the show, and that’s only possible with a full commitment from the musicians. “It’s both immersion and association,” says Clift of the process of becoming a Bee Gee. “You have to hear their voice in your head. You have to have the mannerisms to the point where you can ad-lib in character.”
