"Epona's Song - The Legend of Zelda: Ocarina of Time 3D" is a high quality rip of "Epona's Song" from The Legend of Zelda: Ocarina of Time 3D.
Joke[]
This is a poorly-played kazoo cover of the song. Later at 0:08, it's various audio clips of the Youtuber Ethan Klein, from h3h3productions, coughing, to indicate of how the kazoo player's throat hurts after blowing into the kazoo too hard.
