The playhouse's folklore is anchored by John Steven McGroarty, the playwright and California political figure who wrote the Mission Play and is locally remembered as Uncle John. McGroarty served briefly in the United States House of Representatives and was named Poet Laureate of California; he is the central named figure in the building's folklore.

A recurring backstage detail describes a preserved scenic drop from the original Mission Play production that occasionally swings unprompted during high school musical rehearsals on the stage. A separate account from a 2003 production of The Music Man describes a figure visible in the second-story window of a scenic house on stage; staff, crew, and audience members reportedly observed the figure on the venue's live monitor feed. The figure was identified after the fact by older staff as Uncle John. The folklore notes that no ledge or other physical support exists in the scenic element that would allow a person to stand at that window.

Additional recurring elements include accounts of a child reportedly moving through the upstairs corridors and a former stage manager reportedly observed in the building after hours. A widely retold detail about underground passages used as Depression-era catacombs and sealed off with a brick wall in a men's restroom is uncorroborated in the standard Los Angeles theater literature on the building; that material is presented here as backstage legend rather than verified architectural history.

KiMo Theatre

Albuquerque, NM

The KiMo Theatre opened on September 19, 1927, as the first theater constructed in the Pueblo Deco style — a fusion of adobe Pueblo Revival architecture with Art Deco linear decoration and indigenous cultural motifs. Designed at a total cost of $150,000, including an $18,000 Wurlitzer organ, the theater was built for Oreste Bachechi and named by Pablo Abeita, former governor of Isleta Pueblo, whose entry 'Kimo' (loosely 'king of the beasts') won a public naming contest. In 1977, Albuquerque citizens voted to purchase the building for preservation; restoration was completed in 2000.
