The Dancing Schuberts
In the "Deviated Tonsils" episode (2001) of the animated WB kidvid series Generation O!, the titular band has a brief clash backstage at the tv dance program Dance Jam with the irritating, goody-two shoes, insincere, phony-bologna brother-sister duo, The Dancing Schuberts.
Generation O! has to suffer through their song, "Mom and Dad Know Best," before they can take the stage. Later in the episode, Molly's bratty brother Buzz, torments her by playing a Dancing Schuberts CD.
Tragically, "Deviated Tonsils" turns out to be Molly's medical condition and not the name of any band.
