However, the District police would not issue a license for the use of the building. After being turned down they went after the Ambassador Theater. The captain of that ward mailed out letters to all the area merchants that stated that, "The Psychedelic Power and Light Company was moving into the neighborhood with drugs, long hair and loud music."
