This ride's various incarnations have featured four different English audio tracks. The first of these was for Disneyland's version which opened with the park in 1951. A new track was added when this version was updated in 1959. Sadly, we have no information on the casts of these versions.
Walt Disney World's version, which opened in 1971 with the park, featured another completely new audio track, where Ginny Tyler and Adriana Caselotti were heard.
In 1983, Disneyland's version of the ride was extensively updated and given a new audio track, which was also added into Walt Disney World's version in 1994. This is the most recent/last audio track to be used at either version of the attraction.
