Psycho A-Go-Go (also known as Echo of Terror) is a 1965 crime thriller directed by Al Adamson, starring Roy Morton and distributed by Hemisphere Pictures. The film was originally a straight action thriller, about a psychotic jewel thief who stalks a young woman and her child into the wilderness to get back some stolen jewels hidden in the child's doll. There were a number of musical nightclub scenes in the film, as director Adamson was trying to promote actress Tacey Robbins' singing career at the time. Al Adamson played a cameo in the film, playing one of the jewel thieves who gets shot to death on a rooftop by one of his own cohorts.
