The two final titles in the series was originally produced by Harman and Ising as Silly Symphonies cartoons. But when Disney only bought one of their three shorts, Merbabies, the others were sold to MGM who released them as Happy Harmonies.
The only official home release containing a significant number of the Happy Harmonies film shorts is the Happy Harmonies Cartoon Classicslaserdisc box set. The laserdisc set was released in 1994 by MGM/UA Home Video, which predated the merger of Turner Broadcasting System with Time Warner in 1996. The four-disc set contains 17 of the 37 Happy Harmonies shorts while the remaining 25 shorts include one side of six Barney Bear cartoons, the 1939 animated short Peace on Earth and the 1940 animated short The Milky Way.
