A Pennsylvania high school marching band is raising eyebrows with a halftime performance that commemorates the Russian revolution, complete with red flags, olive military-style uniforms, and giant hammers and sickles.

"St. Petersburg: 1917" is the theme for the New Oxford High School Marching Band. [Shouldn't that be "Leningrad: 1917"?] The band's website features a picture of the group with students holding a hammer and sickle.

"There is no reason for Americans to celebrate the Russian revolution," said one irate parent who alerted Fox News. "I am sure the millions who died under Communism would not see the joy of celebrating the Russian revolution by a school 10 miles from Gettysburg."

The parent, who asked not to be identified, attended a football game last Friday night with his children. He said he was shocked by what he saw.

"It was Glee meets the Russian Revolution," he told Fox News. "I'm not kidding you. They had giant hammers and sickles and they were waving them around."

"Who thought this was a good idea?"

Rebecca Harbaugh, the superintendent for the Conewago Valley School District, told Fox News that the band's performance was "not an endorsement of communism at all."

"It's a representation of the time period in history called St. Petersburg 1917," she said. "I am truly sorry that somebody took the performance in that manner. I am."

"If anything is being celebrated it's the music," she said. "It is what it is. I understand people look at something and choose how to interpret that and I'm just very sorry that it wasn't looked at as just a history lesson."
