Hooray for Everything

This relentlessly cheerful and mercilessly clean cut, whitebread yet multiracial, at least 18-member singing group first appeared in the Bart vs. Thanksgiving episode (11/22/90) of The Simpsons, playing the Superbowl halftime show at the Silverdome, with their tribute to "the greatest hemisphere on earth, the Western Hemisphere! The dancingest hemisphere of all!" Then they go into a cover of the cheesy disco song "Get Dancin" by Disco Tex and his Sex-o-lettes. Their second appearance on the long-running Fox animated series was the "Selma's Choice" episode (01/21/93) where they were featured in a commercial for amusement park Duff Gardens, ruining Lou Reed's "Walk on the Wild Side." The group is a parody of Up With People (who actually did do 4 Superbowl half time shows), Duff Gardens a parody of Busch Gardens and "The Simpsons" a parody of reality.
