According to a Facebook page, "On May 8, 1977, the Grateful Dead performed a concert at Cornell’s Barton Hall. It was the first concert in several years to be held there, and in addition, it became one of the Dead’s most famous and beloved concerts in their 30-year touring history. In honor of the 40th anniversary, the Cornell Chimes will perform a commemorative concert from 6:00-6:30pm. Concerts are always open to the public. People are encouraged to bring blankets and spread out on the lawn around the tower."
