Overworld Theme (Luigi Version) - Super Mario World

"Overworld Theme (Luigi Version) - Super Mario World" is a high quality rip of the Luigi version of "Overworld Theme" from Super Mario World.

Joke
At 0:01, the rip becomes an arrangement of "If You Were Gay" from Avenue Q.

The mix name could be a reference to a misheard line from the Hotel Mario cutscene, where Mario sounds like he says "Gay Luigi" (but really he says "Eh, Luigi?"). This is further alluded to in the Bandcamp track name.
