Apparently yesterday in the Summer Special of their music variety show, Kayō Kyoku, they debut a live performance their next single Gingham Check. I was going to link them from Youtube if there are any, but the two video I found had already got taken down.

This song is, OK I guess, it's got the feel of AKB's summer/bikini songs without an extremely catchy chorus. This song surprises me a bit because I though the song was going to be a bit more, grand, for lack of better words, since it is the election song. While it does have a bit of Yuko solo dance in the end, but overall, the song felt a bit flat due to lacking both identifiable dance move and a chorus that is not quite as catchy compare to their recent singles. But that's just my initial opinion, who know, it might grew on me with a few more exposures.
