The Moon Theme (Alternate Loop) - DuckTales

"The Moon Theme (Alternate Loop) - DuckTales" is a high quality rip of the alternate loop of "The Moon Theme" from DuckTales.

Joke
Starting at 0:15, most of the melody changes to "Great Days" by Karen Aoki and Daisuke Hasegawa, the third OP to JoJo's Bizarre Adventure: Diamond is Unbreakable.

The mix name is a reference to Diamond is Unbreakable featuring a time loop during the section of the anime where "Great Days" is the opening.
