3TV's Yetta Gibson got the lowdown on the show from actor Wade McCollum, who plays Tick, the main character.
"It's a beautiful story about three friends who take a road trip across the Australian outback," he explained. "It's basically an adventure story. ... It's a movie from the '90s adapted into a show."
The costumes -- more than 500 of them -- are nothing short of fabulous, even winning a prestigious Tony Award® in 2011.
Yetta's favorite was a bright jumpsuit -- yellow-and-white striped bell-bottoms -- with shoes attached.
"This might be the most fabulous thing I've ever seen," she said.
There are eight performances left in the run at Gammage -- nightly Thursday, Friday, Saturday and Sunday, plus matinees Saturday and Sunday.
Tickets are $25-$79 plus fees.
