Janet Jackson had to exert a little extra "Discipline" during her concert last night (Oct. 28) at the Palace of Auburn Hills in suburban Detroit.

The singer trimmed a three-song section of her Rock Witchu Tour show, including the sexually explicit "Discipline," in order to comply with a Michigan state law prohibiting simulated sex acts in a public performing space.

Palace officials approached Jackson's camp with concerns about the segment Tuesday afternoon. An arena spokesman says that "we explained the law, asked her not to do it, she complied. We did not ask her to cut the song. That was her call."

In a statement, Jackson's manager Kenneth Crear, who was on site, said that "Janet did not want to disappoint her Detroit-area fans again, so we adhered to Michigan's state ordinance and trimmed the 'Discipline' segment of the show so it would not be canceled."

Jackson's show was a make-up date for an original Sept. 27 show that was one of several postponed when she was sidelined with a bout of migraine-induced vertigo.

During the segment, Jackson usually pulls a male fan from the crowd, ties him down and "molests" him while her dancers mime various sexual acts, including masturbation. She's done the same thing on previous tours, including performances at the Palace and other Michigan venues.

During her encore Jackson explained the omission to the crowd of 8,000 and apologized, adding, "We hope you enjoyed the show we gave you." She made no mention of the postponement, however.

Jackson wraps up the North American leg of the Rock Withchu Tour on Saturday at New York's Madison Square Garden.
