Greta McNabney was legally blind when she performed in this show. Before each performance, she was led to her seat at the side of the stage by either the director or the stage manager.
The show's intro music was all songs by The Beatles performed by other artists. All the songs in the show were done by The Beatles (not live, of course!).
Greta McNabney had her lines memorized for the auditions.
During one scene, "Hector" the mouse actually made an appearance on stage. Fishing line was laid on the stage with a fake mouse tied to one end. When the girls saw the mouse for the first time, the line was pulled across the stage, dragging Hector with it. It was a very fast entrance and exit and only visible to the first four or five rows of the audience but judging by the number of squeals from those in the audience who saw Hector, the effect worked very well!
This was Greta McNabney's final production. She passed away a year later. A videotape of her performance was presented to her family.
