The childhood song, "The Wheels on the Bus", was first published in which year?

The song's first published appearance occurred in volume 25 of 'American Childhood' (1939). While it is not concretely proven who wrote the song, a Boston, Massachusetts woman named Verna Hills (1898-1990) is often credited as the possible creator.

The 'Wheels on the Bus' is a cyclically-structured song that makes it easy for children to learn and participate in groups, as well as perform the associated hand motions. Its melody is based on 'Here We Go Round the Mulberry Bush', a popular direction-dance song.

The original song mentions the wheels on the bus, followed by the wipers on the bus going swish, the horn on the bus going beep, and the people on the bus going up and down. Other verses were added in later years.
