On MBC ‘Beautiful Concert’ aired on May 22nd, TTS performed ‘Twinkle’ and ‘Baby Steps’ as previously posted, and showed their wits in replying to questions directed at them by the MC.
In reply to MC of the show, Hong KyungMin’s question, “What was the reason for forming a unit consisting of 3 members out of the 9 members in Girls’ Generation?”, Taeyeon said, “The other members have their own acting activities. The three of us wanted to put more focus on music.”
After that Hong KyungMin asked, “If TaeTiSeo were to recruit one person into the unit, who would it be?”. Seohyun replied, “Probably it’s Hyoyeon. I think it will be great as Hyoyeon will be dancing while the three of us are singing.”
Tiffany added, “As Hyoyeon is participating in MBC ‘Dancing With The Stars 2′ recently, I think her Rumba dance would go well with our music”, expressing her admiration towards Hyoyeon’s dancing skill.

SNSD Korean 
they do seem pretty “awkward” dancing while singing Twinkle on stage especially because none of them are strong dancers.
I absolutely agrees with u !

i think they are good dancers but
hyoyeon is the real pro when it comes to dancing
thinking of her solo dancing in “into a new world” and “genie”
still hoping that all nine of them wants to focus on music again though
i am somehow missing the “energypill” sunny
“I think it will be great as Hyoyeon will be dancing while the three of us are singing”
It just seems like a polite way of saying that HyoYeon can’t sing. I expect more from you SeoHyun =P
Ok, maybe she was only trying to avoid obvious answers or to cheer HyoYeon up, but I can’t see that working anyway. Adding another vocalist (Jessica or Sunny) would be great, but someone just to be dancing around while they sing? I thought they already have a few back dancers for that.
I think TaeYeon and SeoHyun are both decent dancers with consistent performance each time. Even Tiffany has improved a lot. On top of that, they sing live. This sub-unit is super.
i think that’s a good idea to put hyo on this group..
maybe a lot of people think when seohyun talk about hyoyeon just like a comfort way to tell about hyoeon vocal skill..
but i think that a good way to tell about the 3 dance skill..
hyo who very confidence about dance skill can be dinamo in the group, and talk about vocal skill, i think if she join this sub group she will be improve a lot, since this sub-group more focus in vocal skill rather than dance skill..
but if you see the mv or stage perform, they just do a simply coreo, even in their single twinkle..
so i think don’t judge seohyun words and quote just on iffy part..
TTS is great… But nothing beats having all nine together. It’s how they compliment each other s strengths that make SNSD what it is:)
i hope TTS will win again in Music bank tomorrow…fighting
everyone notice that hyo is like the most loved member by all of snsd *thinks back to paridise in phuket* gotta love/admire her dancing ability
I don’t like it that much when they always say that the three of them were in the sub-unit because they want to focus more on music, it’s like saying that the others do not want to sing or be more involved in the music industry or to grow more as girls’ generation. 😦 I don’t know but I just felt like that. 😀 I just feel that they should say something else.
or maybe I misunderstood it? 😀
Well, I think that a fabricated speech. Of course they didn’t ask for this sub-unit. They do as they are told, so that’s why they’re doing it. That’s the way I see it.
