ABSTRACT
Self-Service, a piece without spectators, was performed in the summer of 1967 in Boston, New York, and Los Angeles. It spanned four months, June through September. Thirtyone activities were selected from a much larger number. Their time and locality distribution were determined by chance methods. Participants selected events from those offered for their city; each had to pick at least one, although doing many or all was preferable. Details of time and place were flexible within each month; choices made from month to month overlapped, some actions recurring.
