Is it true that concerts were banned on campus at one time? Why was that decision made?

Beginning in the 1960s, a number of well-known musicians played at student-organized concerts in McDonough Gym, including Ray Charles (1963), Peter, Paul & Mary (1964), the Kingston Trio (1965), Johnny Mathis (1966), The Lovin’ Spoonful (1967), the Four Tops (1968), The Who (Homecoming 1969), the Grateful Dead (Homecoming 1970), and Traffic (November 1970). After incidents at the Grateful Dead concert and the Traffic concert (which was attended by 6000 people, 2000 more than fire regulations permitted), the University administration suspended concerts on campus. According to Vice President for Student Development Dr. Patricia Rueckel, this move was prompted by a number of considerations - overselling of tickets, “flagrant violations of drug laws”, and “general havoc within the gymnasium.” The ban remained in force until 1971.
