A video clip has surfaced on YouTube from Girls Generation rehearsing for SMTOWN in Taiwan showing the girls taking a tumble whilst on a moving platform.
The clip looks to have been shot by a bystander in the stands while the girls were practising for their upcoming “SMTOWN Live World Tour IV” in Taiwan.
Seohyun, Hyoyeon and possibly Tiffany were standing on a moving platform, driven by a staff member. While the staff try and decide how to manoeuvre the vehicle with the platform on top, they run into trouble. The sharp jerk causing all three members to loose their balance with Seohyun falling over.
All three members appear to be fine after the incident.
