We spent Sunday afternoon at the Sadecky’s Puppets studio/workshop in Tarentum, Pa. Carolyn recorded an audio track for a musical adaptation of “Heidi,” to be synced with performances of live puppeteers touring across 9 states during the coming school year.

Mr. Sadecky, who has been performing with his puppets since the early 80s, was charming but also thorough.

He worked patiently with Carolyn to deliver the performance he wanted. “That was too formal,” he kept saying. “I want you to slur that line a little.”
