I just listened to Davichi's original, and I actually like Fany's version better...she has a sweeter voice. Also, 0:05 I love how Fany, Yuri, and Sooyoung looked at each other, like "OK, let's do this". SNSD members are so close, and work together so well.
I think the problem is with the question, and not with TaeNy. If the question were, "Which member do you wish were a guy so that you can date him (her)?", then Fany would definitely have said, "TaeTae, my hubby!!!!".... Of course, Taeyeon couldn't say anything; that would be too obvious.
I wonder what made them so mad that all 9 members cried at the same time.
