Wondergirls and Girls' Generation's Performance in Music Bank yesterday was actually a cross stage since they didn't perform together in one stage. SNSD performed WG's Tell Me and WG performed SNSD's Kissing You separately.
Here is the link of their performance of Kissing You.WG also performed So Hot.
The performances are both awaited performances of both group fans. All I can say is that it is a must seen vids.
