As if the release of the English version of their song "Let's Go" wasn't already enough of a treat for fans, the superstars of G20 are back with some more action for fans! A behind the scenes/making of video has also been released, revealing more shots of the 20 idols recording and fooling around at the recording studio. Just seeing all twenty artists in one video is overwhelming as it is, but once the camera shows how normal and goofy most of them are, it brings a touch of reality into our perception of the artists. Check out the cute video below!
