- Non-Singing Voice: Even though a number of the Letter People's voice actors were shown to be capable of singing (Miss O in particular was voiced by opera singer Jane Deeken), the show opted to use the songs from the teaching program on which it was based, for most of the Letter People's introduction songs. Mister S' song is an exception, having been re-recorded for the show with Joneal Joplin.
- Older Than They Think: Predates the other educational puppet show with animated segments and frequent musical numbers by a good four years.
