Pillot was also a writer of songs, the most popular of which were As a Snow White Swan and Let Not Your Song End. Most of Pillot's later writing was sacred music. He also wrote poetry. In 1955 he and artist Grace Spaulding John, in cooperation with the River Oaks Garden Club, produced a prose book, Azalea, the story of a real dog and two iron dogs that had guarded the Pillot residence in Houston for more than 100 years. In 1965 the family home was given to the Harris County Heritage and Conservation Society and moved to Sam Houston Park, where it was restored, furnished, given a historical marker, and opened to the public. Pillot was a member of the Poetry Society of Texas and the 1953 president of its Houston chapter. He never married. He died on June 4, 1966, and was buried in Glenwood Cemetery, Houston.
