During the SBS's Big Idol Show, SNSD had a special performance for their fans, almost as a thank you to the fans that have stuck with them since the beginning.

SNSD performed their debut single "Into the New World", a song they haven't performed on TV since 2007. This was definitely a treat for their fans, and it's always interesting to see how much idol groups have changed over the years in terms of image and music.

Before the performance, we were showed scenes of them rehearsing for it in the dance studios. The transition from dance studio to stage at 3:30 was lovely.



And here's their MV for Into the New World for those that haven't seen it.



Hyoyeon, Sooyoung, and Yuri also provided a few nosebleeds with a short dance performance of Black Eyed Peas' "The Boogie That Be" and Basement Jaxx's "Break Away"



And for good measure, they ended it with Gee.
