Also, T-ara performed "Sexy Love" on today's SBS Inkigayo, seemingly in one take (or at least with no costume changes), definitely in front of an audience, though I read on a comment thread in advance that this was recorded several days before the broadcast (not that I always believe what I read). And I wouldn't be surprised if the audience was preselected.

Hard to tell, given the robot concept, but in this performance more than the other two they seem confident, glad to be onstage. Hyomin gives a smile near the end, as if to say, "So there!"
