24 days of singles day 12: Namida Surpise! and Shonichi and FIRST LOVE

This single notably features a fair difference to the previously standard format.

The Senbatsu for Namida Surprise is:
Team A: Itano Tomomi, Kitahara Rie, Kojima Haruna, Shinoda Mariko, Fujie Reina, Takahashi Minami, Maeda Atsuko, Minegishi Minami, Miyazaki Miho.
Team K: Oshima Yuko, Ono Erena, Kasai Tomomi, Miyazawa Sae.
Team B: Kashiwagi Yuki, Sashihara Rino, Nito Moenon, Watanabe Mayu.
Team Kenkyuusei: Komori Mika
Team S: Matsui Jurina, Matsui Rena.

So here we have the first single to feature a Kenkyuuei, unless I've misssed one previously.
Namida surprise is about surprising someone on their birthday with the rest of the class, specifically when turning 17. On the PV, it starts with the girls in class and Maeda daydreaming about the teacher giving her flowers, and Haruna passes a note that goes through the class, as we start getting to the end of the day. As the bell goes and the music starts, and some of the girls cover Maeda's eyes and lead her out. The girls lead her through the corridor blindfolded, with obligatory dancing throughout, but no singing for Maeda, though she does a fair bit of dancing. She takes the blidfold off in front of some shroud, which falls to show they're in the gym, as the others start dancing to the chorus of 'Happy, Happy Birthday'. As the second verse opens a bunch of non-members reveal Kasai holding a cake, but she trips on a tennis ball and the cake goes flying, but Minegishi catches it and throws it to Yukirin, who poses with Moeno and Myao for a picture by Mariko and Mayu.We then go outside, where the goals are in groups posing before Maeda, Itano and Yuko come to mess the poses, followed by some others. The second chorus is in the cafeteria, accompanied by some breakdancing teachers and dinner ladies. We then get a round of 'Happy Birthday to you' as Maeda parts the sea of people before coming to Kojiharu who has the cake. After that it's mostly the dance version.

Shonichi is, surprisingly not sung by the Senbatsu, it's actually by Team B, and I'm going to attempt to list the members at the time.
Team B June 2009: Kashiwagi Yuki, Watanabe Mayu, Sashihara Rino, Nito Moeno, Saeka Mika, Urano Kazumi, Kohara Haruka, Hirajima Natsumi.
The song is about working hard so you can make it onto the stage for the first time, and putting in the effort to do so again.

FIRST LOVE is unique among the tracks on the singles as it's solo by Ono Erena. It's basically about your feelings when falling in love for the first time (never!) and how everything seems to change.
