Table schema:
CREATE TABLE Participants (Participant_ID VARCHAR); CREATE TABLE EVENTS (event_id VARCHAR, Participant_Details VARCHAR); CREATE TABLE Participants_in_Events (event_id VARCHAR, Participant_ID VARCHAR)

Question: Which events id does not have any participant with detail 'Kenyatta Kuhn'?
SQL: SELECT event_id FROM EVENTS EXCEPT SELECT T1.event_id FROM Participants_in_Events AS T1 JOIN Participants AS T2 ON T1.Participant_ID = T2.Participant_ID WHERE Participant_Details = 'Kenyatta Kuhn'
