Strange Fruit by Billie Holiday

Maori, wedding chant.. Very emotional. Everyone in the party began the Huca Huca Huca, it slowly became more and more intense. Then a climatic HUCA, HUCA, HUCA and STOP..... I’ve never seen anything like it.. I was very honored... They became one family from two... A thousand years old tradition...

BTW no pictures... steal your spirit... no jokin’ matter, wind up "part of" the wedding feast.. Yup they use to eat folks... Long Pig...

Regards

All songs are unique, or should be.  Except those that are plagiarised, which is many.

By the way, 'most unique' is not a useable expression.  'Unique' means that there is no other item the same.  A thing is either unique or it is not.

OP should have written 'most unusual' or suchlike.
