The clip comes from Red Cat Reading and is titled Go Go Go, a song written for undokai, the annual sports day held in Japanese schools. Its Japanese title invites everyone to sing along, and the track was made for ouen gassen, the organised cheering contest between teams, complete with simple choreography children can copy. Short excerpts later circulated on soundboards as a wholesome cheer, separate from the full classroom song. It remains popular because the chant is language light, instantly understood, and works for any team entrance or school celebration.
