Our class chose the song "Childhood" for the art festival. It was not very easy to sing and the dance was not very good either. Why not try the song "What a Beautiful Campus", which is more lively and skips the school anniversary. Girls' Generation's gee is also very good. There are dances in the video, and some classmates dance. The effect is good. Wearing casual clothes can reflect the liveliness and cuteness of the children.
Hope this helps. (*^__^*) Hee hee...
