Amanda Goodsort, once a Boston society belle, has journeyed to Arizona to find employment so that she might support her infant daughter.  Alas, she must perform on the stage of Tombstone’s famous Birdcage Theatre, where soldier lads and silver miners come to gawk and applaud!  In order that her true identity never be revealed, Amanda sings in disguise and is known far and wide as The Masked Canary; but to civic leaders like the tenacious Flora Courtland, who is determined to drive her out of town, she is...  "the shame of Tombstone!"  Alas, the wily villain, Judge Mortimer Harshly, and a pretty cohort, Peachy Jamm, discover Amanda’s secret and decide to blackmail her.  The side-splitting action begins on the day Amanda’s grown daughter arrives in town with her two companions, Lonely Wolf, a Harvard-educated scout, and Lt.  Pete Bogg, a manly chap who has everything...  including PX privileges and a future pension.  An outrageous company of funny characters add to the confusion:  Cantankerous Ol’ Timer; Wing Tip, the Oriental philosopher who is available for witty sayings and tea-brewing; Fifi, the French maid from Bisbee.  But above everything is the sheer nastiness (and comic genius) of the Judge.  All ends suitably with the meanie’s defeat, Amanda’s vindication and a sing-a-long to keep the audience smiling.
