Voting begins today in the dining halls for a three-day-long non-binding referendum on whether the Undergraduate Council should sponsor a campus-wide concert featuring the rock band. The Grateful Dead.

But today may be the only chance to vote for or against the Dead, if Dean of Students Archie C. Epps II--whose decision is expected today--cancels the project.

Although the council has found a sponsor to pick up the Dead's $100,000 tab, logistical considerations such as crowd control and use of the Harvard Stadium--the proposed site of the concert may lead Epps to rule against the concert.
