Yeah, I know, but what I mean is it's probably very unlikely.
If they do perform solo/group songs, it's going to [probably] be:
Nacchi: Amasugita
Maki: Some Boys
Ayaya: a GAM song, maybe? If not, Dearest or Namida
Yuki: Omae no Namida
Yuko: Urara
Kaori: I dunno. A song from her 4th album?
Atsuko: an old T&C song? Cause that would be kickass
Melon: Onegai Miwaku?
Country: Kakumei Chikku
Kei: I can see her performing an old MM song. Summer Night Town, anyone?
On another note, I'd like to see Maki cover Aisucream to My Purin.
