During rehearsals for today's episode of KBS's 'Music Bank', a lighting accident caused a major shift in schedules for participating artists. On August 12th, rehearsals were going as planned at the KBS Public Hall until it reached Seo In Guk's turn. During his rehearsal, the lights shut off on stage, causing a halt in the rehearsals. Seo In Guk left the stage to be on standby, leading those after him to be put on hold for an indefinite amount of time. The representative explained, "Fortunately, it wasn't a big accident as we thought and recording was only paused for a brief moment. Rehearsals will begin immediately after lighting is restored. However, due to the delay of the pre-scheduled rehearsals and recordings, artists who were originally scheduled for pre-recordings may just have to perform live." Source + Photos: Newsen via Nate
