Deasy left Manson's home after three days, "in a state of drug-fueled paranoia". Deasy continued to record with leading musicians, including Frank Sinatra, Ella Fitzgerald, Barbra Streisand, Chet Baker, and Mel Tormé. His guitar playing has appeared on the soundtrack of many films including "The Graduate", "Guess Who's Coming to Dinner", "Duel", "Bullitt", and "Dirty Harry", as well as on many commercials. From the early 1970s onwards after becoming a born again Christian at the 1969 Billy Graham crusade in Anaheim, California, Deasy became increasingly involved with Contemporary Christian music, producing and writing songs for several successful albums, often in conjunction with his wife. In later years, he has had a parallel career as a motivational speaker, and since 1988 has run a "Yes To Life" educational and inspirational program in schools and colleges in the US, Canada and Europe. The Deasys also co-pastored Rock Church Southeast in Port Arthur, Texas, until it eventually shut its doors when Hurricane Harvey flooded the building.
