Set in ancient Rome as its appealing title suggests (that title being one of the best things it has going for it)  A Funny Thing Happened On The Way To The Forum is a zany comedy with music.  A slave, Pseudolus, makes the deal to acquire for his master, Hero, the beautiful Philia, in return for which Hero will set him free.  Philia is held in the house of the pimp, Marcus Lycus, who purchased her on behalf of the Great General, Miles Gloriosus whose arrival is imminent.   With Hero’s parents out of town, Pseudolus sets to work keeping Philia away from Miles Gloriosus and nabbing her for Hero, the slave’s on-the-spot inventiveness conjuring various ruses involving potions, hideouts and disguises leading to humorous false hopes and a romp of mistaken identities.
