"Koisuru Velfarre Dance ~Saturday night~" is MAX's debut single released under Avex Trax.

It is a Japanese language cover of the song "Saturday Night" released in 1994 by Whigfield.

As the song was originally recorded for the opening of Avex's Velfarre club, it was meant to be MAX's only release as the group was created solely for promoting the club.

Besides new lyrics, MAX's version contains an entirely new comedic spoken word verse.

A music video for the song was filmed in the Velfarre night club and features MAX and club-goers performing the same dance routine popularized by Whigfield.
