Context: For an artist of his stature, very little is known about Vangelis' personal life and he rarely gives official interviews to journalists. However, in a 2005 interview with The Daily Telegraph, Vangelis talked openly about various parts of his life. He stated in the interview that he was "never interested" in the "decadent lifestyle" of his band days, choosing not to use alcohol or other drugs. At the time of the Telegraph interview, Vangelis was involved in his third long-term relationship. When asked why he had not had children, Vangelis replied:  ...Because of the amount of travelling I do and the nonsense of the music business, I couldn't take care of a child in the way I think it should be taken care of.  It is not publicly known where Vangelis generally resides; he has stated that he "travels around", rather than settling down in one specific place or country for long periods of time. As a hobby, Vangelis enjoys painting; his first art exhibition of 70 paintings was held at Almudin in Valencia, Spain in 2003 and then toured South America until the end of 2004.  Excerpts from other interviews mention that Vangelis has been married twice before. In a 1976 interview with Dutch music magazine Oor, the author wrote that Vangelis had a wife named Veronique Skawinska, a photographer who had done some album art work for Vangelis. An interview in 1982 with Backstage music magazine suggests that Vangelis had previously been married to a singer named Vana Verouti, who had performed vocals on some of his records, performing for the first time with him on La Fete sauvage and later on Heaven and Hell.
