You went to the wedding? What was that like? To whom was Horn married?
From my research so far it appears that Alex Horn hooked up to Sharon Kulko Horn (a.k.a. "Gans") in 1969 after his split with Anne Burridge (now "Haas"). But, it seems Alex and Sharon did not marry until 1972, according to the Supreme Court Kulko custody case records.
According to an excerpt from "Taking with the Left Hand", Alex Horn was also married to a woman called "Carol". Ever heard of her? I would assume this was before he met Anne Burridge of England.
"Though claimed to be a Fourth Way teacher, he himself never had an authentic Fourth Way teacher. The level of his understanding of the teaching was based on what he could pick up from Fourth Way books and
from his one-time teacher, the actor-director Alexander Francis Horn. Horn, himself a faux-Gurdjieffian without any real connection to the
Fourth Way, had based his own understanding on books and on that of his first wife Carol, a student of John Bennett's ten-month experimental program—an eclectic melding of the Fourth Way with other teachings and
practices. Horn first taught in New York and later in San Francisco where he created the Theatre of All Possibilities, a theater which purported to double as a Fourth Way school. Horn financially exploited his students, manipulated their lives, often physically brutalizing them—all in the name of the teaching.
