Leaders of the Whiffenpoofs, Yale University's world-famous glee club, say their sound isn't changing, but they are ending their more than century-old tradition of being a male only a cappella ensemble. 

The move, they say, is designed to give more people access to what can be life-changing travel opportunities and music industry contacts that come with being a member of the nation's oldest collegiate a cappella group.

Right. It couldn't possibly have anything to do with political correctness, could it?
