Recently, fans discovered an old video of 'Forever Young' being played at YG Entertainment three years ago.
It was taken by a fan who happened to record a video in front of YG Entertainment's building in November 2015 while a song was being played.
If you listen to the song in the video, ROSÉ and LISA's part can be heard very clearly.
As it was uploaded on the fan's social media account where the video cannot be edited, it is for sure that the song was produced before November 2015.
After the discovery, the video started to go viral among fans.
Fans have been commenting on how surprised they were to find out that 'Forever Young' was ready to be out even before the group's debut in August 2016.
