Okay, so the three aforementioned must travel a significant distance to do a show. All three are at crucial points in their lives. I cannot remember the names of the characters so bear with me. The most flamboyant and outrageous of them is who I take to be the youngest. He is the one that got his mother to pay for the bus by which they make their journey. A brash fello
The character who is the dramatic focus is somewhat older. We learn that not only is he married, but he has a son. This is the crux of the movie.
The final character is played by Terrence Stamp. No one else in the movie is familiar to me. Stamp is older. He has just suffered the loss of a lover.
And there we are. They travel into the Outback on their bus, called Priscilla of the Desert, and bicker and have adventures. Stamp is the fulcrum. The other two are wacky and outrageous, while he is stately, which is a nice balance. It is a graceful, warm performance. The humour is at times goofy but the movie is genuinely warm-hearted without excess. Lots of ABBA, 70s disco, and the like.
