To cover legal fees defending the Mime Troupe, benefit concerts were organized. The first, in the troupe's Howard Street studio featured Jefferson Airplane, Allen Ginsberg, The Committee, Sandy Bull, The Mothers, Peter Orlovsky, and the John Handy Quintet. It netted $2,000 in donations. The second “Appeal for Continued Freedom of the Arts” was organized by Bill Graham and held at the Fillmore. Over 2,000 people paid $1.50 to hear Big Brother and the Holding Company, the Grateful Dead, Quicksilver Messenger Service and Jefferson Airplane. The financial support of the bands reflected the troupe's mission of convincing artists to stop working for the sake of money, to instead work for the people and social change. This lobby card was used for the May, 1965 performances of the San Francisco Mime Troupe’s presentation of “The Exception and the Rule.” It was the first show produced by the now legendary “Bill Graham Presents,” Bill Graham Presents, the fountainhead of U.S. rock and counter-culture music for more than three decades.

This issue of Synapse 4, published in 1965, is another great example of a Mimeo Revolution publication. The cover proudly proclaims contributions by Robert Duncan, Phillip Whalen, Gry Snyder, Joanne Kyger, George Hitchcock, Lew Welch, Lenore Kandel, George Stanley, David Maltzer and others.
