Alec Morris | Happy Birthday Ami! (Sang By Michael Jackson) @alecmorris7979 | Uploaded 6 years ago | Updated 14 hours ago
Here's "Michael Jackson" (o Navi) singing to Ami on her birthday. How nice for him.

Also, Yumi did some vocalizing in the song.

Nonetheless, Ami loved her birthday gift from "MJ" himself.

I own neither material.

(P.S. If it was really Navi, then he didn't really sound like a gruff guy from Brooklyn.)
