There is a Disciples of Christ-sponsored school in Canton, Missouri - Culver-Stockton College - with which he made have had a relationship...PARTICULARLY since the school apparently has an annual William Spencer Johnson Piano Scholarship Competition
Doing a search for you, I first discovered (before the piano competition thing) that during that school's centennial celebration in the early 1950's, he wrote the music for a centennial hymn sung in a celebratory pageant.
He did some instrumental (oboe, etc.) arrangements of some Bach (not J.S.) in the early '40's.
This may be totally incorrect, but he may have been married to a lady named Shirley Weeden Tompkins.
