Some other Gemmy products also use the recordings of the songs from Harry and Rocky (e.g. Dancing Dragon) therefor, those items feature the monkey noises in their songs too. Some of them (mostly Halloween) had the recordings as well.
Jingle Jungle Jim has the same recording as the dancing douglas fir tree.
