Their conductor is described as a Racing Fan, although the The Clappy Trio are the ones seen forming a crowd in Freeze Frame. One Chorus Kid appears in Munchy Monk in Rhythm Heaven Fever, where the titular monk is seen training by feeding him on a moving train. The Chorus Kids have been observed to perform in a variety of locations, such a featureless white plain, the beach, a spaceship, at Rock 'n' Roll Hall during the Battle of the Bands, and a factory. The clappy member decided to leave the Clappy Trio with consent from his colleagues and take the chorus under his wing as their conductor, but he claims to be just there to help them along as 'They're the stars, and I try to stay out of their way.' One day, while the Clappy Trio was performing on a street corner, one of the members saw another group nearby, a chorus that just couldn't get their act together, because the third member was so nervous that he couldn't stop singing out of turn.
