WASHINGTON (CNN) -- Supreme Court Justices Ruth Bader Ginsburg, Stephen Breyer and Anthony Kennedy played a role in the opening night of the Washington Opera's 2003-2004 season Saturday night, at the DAR Constitution Hall.

They came on stage during the raucous party scene in Johann Strauss Jr.'s comedic opera "Die Fledermaus," about mistaken identities and romantic temptations at the hands of a friend seeking revenge.

Wearing judicial robes, they were introduced as distinguished guests of Prince Orlofsky. Except for a colorful fan carried by Justice Ginsburg, they looked as if they had walked right off the bench onto the stage.
