World Series Game 4: George W. Bush, Lyle Lovett Key Pre-Game Festivities

In the World Series, every game requires its own festivities. Saturday, the Rangers trotted out Nolan Ryan, Kelly Clarkson, and Martha Plimpton. And Sunday, they're aiming even higher.

The ceremonial first pitch will be thrown by George W. Bush, who was the 43rd president of the United States. GWB was the Rangers' managing general partner from 1989-1994, and was a part of the team's ownership group from 1989-1998. He'll be accompanied to the mound by his father, George H.W. Bush, who was the country's 41st president. The pitch will be caught by Nolan Ryan, who seems to be involved in everything.

The national anthem will later be performed by the Klein, Texas-born Lyle Lovett, a four-time Grammy award winner who's sure to get a better reaction from the crowd than Clarkson did.

Following that, the first game ball will be taken to the mound by Rangers Hall of Fame announcer Tom Grieve, accompanying Don Mitchell of the Boys and Girls Club of Dallas.

Later on, during the seventh inning stretch, United States combat veterans 4 Troops will perform God Bless America.
