The opening song for the school trip episodes (7 and 8) was sung by Group 4 (Nagisa, Kayano, Karma, Sugino, Kanzaki, and Okuda) instead of Utatan, so yeah, there are some variations in the Group 4 version of the song.

The Group 4 version has the boys sing "Nan nanda ira ira no hadou wa" and then the girls sing "Bokura no sonzai no shoumei."

It's too bad the other groups didn't get to sing their own versions. Kinda wish Group 4 got to sing more openings too, but that unfortunately never happened.
