Having had more UK hits, such as "It's Only Make Believe" and "I Will" (written by Dick Glasser, not to be confused with the Paul McCartney song), both in 1964, and "In Thoughts of You" (1965), Fury began a lengthy absence from the charts in 1967, and underwent surgery for heart problems in 1972 and 1976 which led to his abandoning touring. Despite spending many weeks in the charts, Fury never achieved a number one single, but he remained popular even after his hits stopped. "I Will" became a US hit for Dean Martin (1965) and for Ruby Winters (1977).
