I applaud the creativity of the hip-hop video even more than the song. I also found it interesting that one Black man was carrying a flute that he said was generations old and given to him by his Irish ancestor.

I also noted that the leprechaun was supposedly seen up in a very tall tree-I'm not sure how Irish that belief is {somehow I always associated leprechauns with hiding behind bushes near the ground}.

But belief in spirits inhabiting trees is very much a part of traditional African religion. Some trees are more sacred than others because they are the abode of a spirit or spirits. And that belief traveled to the Caribbean and to the USA South with enslaved African Americans.

See this excerpt from this article: http://www.flmnh.ufl.edu/caribarch/Ceiba.htm

"Various beliefs in supernatural spirits were brought to the West Indies from Africa by enslaved peoples. It is likely that these beliefs also were influenced in the 16th century by the last remaining native peoples One of the modern words for spirits of the dead in the West Indies -- Obeah -- may originally have come from the Taino name (see Zombi for another example). In 1936, Anthropologist Zora Neale Hurston received a Guggenheim Fellowship to study Obeah in the West Indies. She lived in Jamaica from April to September and attended numerous local ceremonies. Jamaicans believe that "duppies" (spirits of the dead) live mostly in silk cotton trees and almond trees. For that reason neither tree should be planted too close to the house because the duppies who live in them will "throw heat" on the people as they come and go. Duppies are responsible for various kinds of mischief and can hurt a living person such that medicinal cures (including "balm baths") must be sought from local healers who serve as both "doctor and priest." We should keep in mind that while modern Jamaicans recognize that belief in duppies is a part of their heritage, the practices associated with these beliefs have faded with time.

This online article about the silk cotton tree also talks about the Taino {of the West Indies} belief in tree spirits and other spirits. With regard to the traditional African belief, I'm not sure if there is/was any specific spirit that was associated with a pot of gold, but certainly Ghana, West Africa and other parts of Africa} are known for their gold deposits. And praying/singing/dancing/invoking spirits & gods who received their powers from a Supreme Deity was said to help a person get and keep wealth is an integral part of traditional African religions.
