Dalhousie University is apologizing for a full monty performance that took place on campus Friday night.

It happened during a 50th anniversary for the department of health and human performance at University Club, a private facility for staff and faculty.

According to people who were there, two MCs of the event took to the stage and undressed to Def Leppard's Pour Some Sugar on Me.

"We certainly do apologize to anyone in attendance at the event who were offended," said Dalhousie spokesman Brian Leadbetter.

200 apology emails sent

Attendees said the two men, both faculty members, stripped down to a pair of flesh-coloured underwear.

There were about 200 people in the audience — all of them will get an email this week from the department's dean apologizing.

"We're certainly going to be connecting with those who were in attendance at the event as well as those who were MCing the event to get further information about what transpired," Leadbetter said.

'Respect standards of appropriate behavior'

Leadbetter said there have been a number of complaints about the performance, but he wouldn't say how many.

CBC News spoke with some people who attended the performance who said they were not offended and that it was all in good fun.

That's not the way the university sees it.

"We expect members of our community to respect standards of appropriate behavior," Leadbetter said. "And I believe [the dean] asked people who may have had concerns, or expressed concern about the event to contact her directly."
