After School had their goodbye performance on "Music Bank." 

On the 27th on KBS2 "Music bank" was a special commemorating the London Olympics.

After School showed their support for the Korean soccer team by singing, "Oh Victorious Korea." They also left a special message for the athletes: "We wish health on all the players."

After their interview, After School performed their last song. On stage they were seen in white and black bathing suit styles, showering the audience with their charisma and sexiness.

They were seen performing their title song, "Flashback," with a sultry gaze and dance moves. The cherry on top was their famous "jjuk buhl" move.

The crowd raved even more at After School's more than usual expressive and perfected performance. However, fans wore sad faces as the modelesque members approached the fans to say farewell.

On the other hand Beast made a flashy comeback after being absent from the music scene for a year and two months.
