OMAHA, Neb. (AP) — A Chicago man’s lawsuit says an Omaha school district should not be using the name “Singsation” for an annual swing choir competition.

Willie Wilson’s lawyers filed a trademark infringement lawsuit on Dec. 3 in Nebraska’s U.S. District Court against the Millard School District, which covers parts of western Omaha. Wilson says that since 1989 he has produced a gospel music TV show called “Singsation” and owns the brand name. The lawsuit accuses the district of trying to pass off the district’s “goods and services as those of Willie Wilson.”

School district attorney Duncan Young says he’s evaluating the complaint. Young says he told Wilson’s attorneys before the lawsuit was filed that the district would not use any logos that “even slightly resemble” Wilson’s logo.
