Not necessarily definitive, but some interesting notes here:

1969, 1977, 1982, 1985 and 1990 runs
Fantasia began to make a profit from its $2.28 million budget after its return to theaters on December 17, 1969. The film was promoted with a psychedelic-styled advertising campaign .... The release is also noted for the controversial removal of four scenes from The Pastoral Symphony over racial stereotyping. Fantasia was issued on a regular basis, typically for exhibition in art houses in college towns, until the mid-1970s.

Disney considered releasing a multi-disc 78-rpm record album of Fantasia's soundtrack in conjunction with the film's 1940 roadshow release, but this idea was not realized. The soundtrack was ultimately released as a three record LP set in sixteen countries by Disneyland Records in 1957 under the catalog number WDX-101. ... The Fantasia soundtrack album contains all of the musical selections but none of the commentary from the film. After stereo LP's became possible, Buena Vista Records released a stereo version of the soundtrack album.
