From the Cavaliers Web site: On Tuesday, May 10, a group of 27 current and recently graduated members of the Cavaliers will appear in a supporting roll on "The Oprah Winfrey Show," as they help create a pseudo-college environment, which includes a marching band (played by the Cavaliers), cheerleaders and a college mascot for a short segment where Oprah and a cooperating sponsor team up to send two sisters to Baylor University and cover their major expenses (tuition, books, room and board) for four years. The segment with Oprah and guest Ty Pennington of "Extreme Makeover" fame took about five minutes to shoot after hours of rehearsal Tuesday evening and Wednesday morning in the Harpo Studios parking lot in Chicago, where the actual surprise takes place. The Cavaliers had been contacted about five days previous to the taping and used their weekend camp to quickly arrange a group to represent the corps the following Tuesday and Wednesday.
