The ever-puckish — or obnoxious, depending on who’s talking — Stanford University marching band has played its last tune for the rest of the school year.

University leadership temporarily suspended all activities of the ensemble on and off campus from Friday through spring 2017, citing “constant and repeated violations of policy” suggesting a “systemic cultural problem.”

The punishment comes after the school’s Organization Conduct Board reviewed four separate investigations into violations of university alcohol policy, student conduct rules, and an alcohol and travel ban from May 2015 — which was put in place to discipline the band the last time the group got in trouble.

A Dec. 1 review from the panel found that the band broke alcohol rules at gatherings and used band funds to rent a cabin at Lake Tahoe, violating the travel ban, according to a letter to band leadership from Greg Boardman, vice provost for student affairs.

“We do not feel that the current leadership or membership is capable of creating the necessary cultural change. We feel there is a total lack of accountability and responsibility in the current organization,” the panel wrote in its review. “As a result, we feel that extreme sanctions are required in this case.”

In the meantime, Boardman will direct a committee to replace the current student-managed band leadership model. The new structure will include direct university oversight by a professional music director, he said.

He warned that the suspension could be extended “if the university determines that more time is needed to produce the desired shift in culture and organizational change.”

Stanford’s band has a long history of conflicts with school officials for offenses ranging from irreverent half-time shows mocking rival schools to violations of alcohol, hazing and sexual-harassment policies.

Violations that sparked the May 2015 penalty “included a tradition in which a band member was given an alcoholic concoction intended to make that individual vomit publicly; an annual trip in which some band members used illegal substances; and a band selection process in which individuals were asked a number of inappropriate questions on sexual matters,” the school said.

But mischief from the musicians dates back decades.

In 2006, the band was suspended after an estimated $50,000 in damage was inflicted on the Band Shak, an off-campus trailer that was the group’s temporary home before the band moved into a permanent facility.

Two years earlier, at Brigham Young University, the band’s dancers wore wedding veils in a parody of polygamy.

In 1991, at Notre Dame, a band member dressed as a nun conducted the band using a crucifix as a baton. Notre Dame banned the band indefinitely.

During a 1986 halftime show at a game against University of Washington, the band drew a two-game suspension after some members dropped their pants and others urinated on the field.

Perhaps the band’s most famous escapade was when members rushed onto the field in the closing seconds of the 1982 Big Game at UC Berkeley, believing that the game was over. Stanford lost after Cal executed five laterals, the last of which ended in a player scoring the winning touchdown as he crashed into a trombonist.
