I would like to see the persimmon tree.

Back then, monkey-themed things were at their peak, and maybe that's why. As for Alvafilm from the 80s, only two drug addicts remembered it, and they never got off drugs. Although, I think the situation has changed now, at least on social media, YouTube, etc. I don't see or hear anything about monkeys anymore, and music from the 80s is more common.
