The song was published in various places through the decades following the late 1950s, including a volume of “constructive recreational activities” for children (1957), a book of drama projects for disabled children (1967), and a nursing home manual (1966). In 1971, Jonico Music filed for copyright on the song, crediting it to Joe Raposo. During the early part of the 2000s, the music Recording Industry Association of America actively prosecuted individuals for downloading music using file-sharing services. Widespread media attention was paid to one 12-year-old, whose downloads included “If You're Happy and You Know It” from Kazaa.
