Meanwhile, shortly after the premiere, Duncan underwent surgery to remove a benign brain tumor behind her left optic nerve. As a result, she lost vision in the eye, but it was not replaced with a prosthetic eye, as some urban myths claim. She lost vision in her left eye, but because the eye still tracked with her right eye, Duncan and her doctors elected to leave her natural eye in place. Though Duncan's recovery from the operation was rapid, CBS suspended production on the show until the following year, after the 12th installment had been filmed; the original series pilot served as the 13th (and final) episode. At first, Nielsen ratings for Funny Face were low, ranking in the lower 50s; eventually, they climbed up to #17, and it was deemed the best-liked new show of that television season. For all her efforts, Duncan received a nomination for an Emmy Award for "Outstanding Continued Performance by an Actress in a Leading Role in a Comedy Series". In September 1972, the program returned as The Sandy Duncan Show, with a revised format and new writers; it also had a new time slot, on Sunday at 8:30 p. m. Critical reaction to the show was similar to that for Funny Face, but without the strong Saturday night lead-in of All in the Family, the ratings sank. After 13 episodes, CBS cancelled the series. In 1976, Duncan played the title role in a TV musical adaptation of Pinocchio, which featured Danny Kaye as "Mister Geppetto" and Flip Wilson as "the Fox". She also guest-starred in a first-season episode of The Muppet Show where, contrary to common misconception, she was not the first to be karate-chopped by Miss Piggy, but she did share a raucous moment recollecting "The Banana Sketch" with Fozzie Bear. Next, for her performance as "Missy Anne Reynolds" in the miniseries Roots, she earned another Emmy nomination. It was then that she went back to Broadway for many years. In 1979, her run as the title role in Peter Pan won her many accolades. She also had replacement roles in My One and Only and Chicago.
