Yankees fan Morissette sings anthem

Grammy winner hides allegiance from home Phillies crowd

PHILADELPHIA-- Alanis Morissette might have been singing at the Phillies' Citizens Bank Park on Monday night, but the nine-time Grammy Award-winning singer/songwriter wasn't ready to switch allegiances.

"I'm a Yankees fan," Morissette admitted, after some prodding.

The singer, fresh off Sunday's ING New York City Marathon (which she ran to raise money for the Maasai Wilderness Conservation Trust), was tapped to sing the national anthem prior to Game 5 of the World Series, a contest that finds Morissette's Yankees just one win away from the championship.

"I love how sports can bring people together in a non-fraught way," said Morissette, who has sung the American and Canadian national anthems at the Stanley Cup Final but was making her baseball debut. "It's not political or anything; it's really an environment with one purpose, although it's very competitive."

And with the Yankees holding a commanding 3-1 series lead, Morissette will watch the game and quietly root on the Bronx Bombers, for fear of upsetting the native Phillies Phans.

But with her pinstripe preference still very much under wraps, Morissette received a warm welcome from the packed house at Citizens Bank Park. Wearing a World Series jacket and boots, the self-described jock belted out "The Star-Spangled Banner" from behind home plate, with fireworks and a frenzy of white towel-waving fans capping off the baseball tradition.

Following Morissette's performance, Phillies Hall of Fame pitchers Sen. Jim Bunning and Robin Roberts each tossed out a ceremonial first pitch, with J.A. Happ and Jayson Werth (who is from the same hometown as Roberts) the welcome recipients.

Among the notable celebrities on hand for Game 5 were actor Jim Caviezel and Biff Henderson. Caviezel is best known for his portrayal of Jesus in "The Passion of the Christ" and is starring in "The Prisoner" for AMC airing in mid-November, while Henderson is a stage manager for "Late Show with David Letterman."

"I'd like to see the Yankees secure it tonight," said Henderson, who also attended Game 2 and was on the field during batting practice. "I don't want to see them take this back to New York."
