As if sweeping the Colorado Rockies by a score of 10-0 was not enough, the Urban Singers – with some help from students in the chorus at San Francisco’s Lick-Wilmerding High School  — opened the April 10 game with their rendition of the  national anthem.

The singers marched into AT&T Park behind Urban Choral Director Brandon Adams, stopping in center field to face an eager Lou Seal, the San Francisco Giants’ mascot, who was standing on home plate.

“It was especially fun to sing with the Lick chorus in order to get a more prominent and powerful sound,” said Urban singer Clara Webby (’15).

After their rendition of the anthem, which lasted approximately 1 minute and 22 seconds, the Blues and the Lick-Wilmerding students walked off the field to a standing ovation from more than 42,000 fans.

“We sounded good and it was thrilling to be 10 feet away from (Giants shortstop) Brandon Crawford,” said May Congdon (’13), adding, “it didn’t hurt that it was a beautiful day at the yard.”

Asked how many times Urban students have sung the national anthem at a major league baseball game in San Francisco, Adams responded that it was “at least eight times” but could not provide more detail.

The Giants went on to shut out the Rockies, behind catcher Buster Posey, who had three hits, and starting pitcher, Barry Zito, who pitched seven strong innings.
