Gunbarrel, Colo. ? A day after attending alcohol awareness classes, 21 members of the University of Colorado marching band were ticketed for underage drinking.

Sheriff’s deputies responded to a party early Thursday morning in east Boulder County. They found numerous intoxicated people, and confiscated fireworks and five beer kegs.

The university recently earned the distinction as the nation’s top party school in a survey by the Princeton Review. Lt. Phil West said the designation was obviously “well deserved.”

Ryan Serpan, 20, the party’s host, told authorities he was celebrating his birthday. The CU junior would not say where the kegs came from, according to an incident report.

“This was not an official band event in any way, shape or form,” CU band secretary Diana Wilson said. “Unfortunately, we cannot control every moment of our students’ time.”

At least six of the ticketed people are squad leaders, section leaders or drum majors in the band. Those ticketed will not participate in Saturday’s performance at the State Fair in Pueblo and must attend alcohol education counseling. They also face action by the CU Office of Judicial Affairs.
