유리 - Save the World Quiz 090530 (cut)
This has all of the major clips featuring Tiffany and Yuri from Girls Generation. But I'm posting it because you can catch a glimps of Jang Yoon Jung (장윤정). Is she still a MC on 1000 Song Challenge? Anyway, she sings a couple of lines from Girls Generation's Gee--I don't think in a Trot style but pansori style? I could be wrong, but her way of singing reminded me more of the latter than the former.
090530 Tiffany & Yuri - 6/6 @ Sebaqui
If you look hard enough you can watch the entire May 30 episode of 세바퀴 online.
An oldie!--Jang Yoon-Jeong - Yeogo joleopban (장윤정 - 여고 졸업반)
