By now, everyone knows that tonight's "surprise" guest--to be featured after 10 p.m.--is Clint Eastwood.
But there were some slightly less-A list celebrities featured on stage as a group of 13 Olympic athletes took the stage to testify to Mitt Romney's leadership of the 2002 winter games in Salt Lake City.
The crowd cheered raucously as Scott Hamilton, who won a gold medal in figure skating in 1984, appeared on stage with the group. Hamilton has maintained his popularity in part as an NBC analyst of figure skating events.
But especially popular was Mike Eruzione, captain of the famous gold medal winning 1980 U.S. men's hockey team, which defeated the Soviet Union in the so-called Miracle on Ice.
"U-S-A! U-S-A!" the crowd shouted with particular verve as Eruzione was introduced. Olympic athletes have a tendency to bring that out in people. Hamilton pumped his fist and chanted along.
Eruzione told the crowd about Romney's efforts to turn around a Olympic games that had been marred by a bribery scandal before Romney was named chairman.
"Just like the Olympics needed Mitt Romney's leaders 10 years ago, America needs Mitt Romney's leadership today," he said.
