The humour, after all, is as innuendo-laden as a Carry On movie, and time has hardly been kind to the songs, many of which were always trashy. These were rammed into the story any which way because a musical needed songs, and, when they do aspire to greater pertinence, mawkishness usually seeps out.

David Harris plays Tick, the drag queen who instigates the technicolour road trip to Alice Springs to meet his estranged young son, taking with him Bernadette and Felicia (Euan Doidge).

Alas the gulf between Sheldon's charisma and that of Harris and Doidge undermines a show that really needs the three leads to be of comparable interest and appeal.

Robert Grubb does a shrewdly understated job of making Bob the mechanic worthy of Bernadette's affections, Blake Appelqvist​ shines as Miss Understanding, and Lena Cruz has a ball with Cynthia, Bob's wife.

Ross Coleman and Andrew Hallsworth's​ choreography is mostly sharply rendered, Brian Thompson's sets remain a flashy delight, and the band and sound are excellent. Less consistent is the singing, the notable exceptions being Angelique​ Cassimatis​, Samm​ Hagen and Cle Morgan as the Divas.

The Divas are also blessed with some of Chappel​ and Gardiner's most stupendous costumes, including the angels-and-gum-leaves creations for the finale.

So, in a shower of charms and flaws, Priscilla​ is once more rolling proudly on, with the MacArthur Park gag the icing on her cake.
