After leaving Dunhill, Sloan recorded an album in 1968 titled "Measure of Pleasure". It was produced by Tom Dowd and released by ATCO. In 1969, Sloan's "New Design" was included on the "Ruby, Don't Take Your Love To Town" album by Kenny Rogers and The First Edition. Sloan left the music scene due to numerous business and legal problems. He repeatedly reported that Dunhill made threatening advances to force him to sign away the rights to his valuable compositions and that the reason for his absence from the music scene was to battle illnesses. After 1969, he did not frequently record or perform until the new millennium. He finally found relief from his long illness with help from Indian guru Sathya Sai Baba. In 2006, describing this period away from the world, Sloan said, "I was ill I guess for a good 20, maybe 25 years. . . . Catatonia for a long time."
