Satisfyingly, although Mr Banks desires to be a different kind of upwardly mobile to Mary Poppins, he is a sympathetic character, surprisingly open to her suggestions.
The villain becomes a witchy governess (a show-stealing Natalie Gamsu), whose brimstone and treacle bring her into a delicious, magical nanny showdown with our superheroine and her spoonful of sugar.
But some new songs - Practically Perfect and Playing the Game - are in slight danger of turning Mary Poppins' self-satisfaction into a harsher, priggish self-righteousness.
And although Pippa Grandison belts out her solo beautifully, Mrs Banks' character is a disappointing throwback - a wife whose one and only wish is to please her man.
Still, American Rachel Wallace as Mary heads the excellent Australian cast with poise and polish, and Matt Lee leads us cheerily through as chimney sweep Bert.
Running at around 2h 45m, it's a little long for a school night, but feels as fast as a ride on the wind. Superb.
