The Hollies soon became one of the most successful bands in Britain; they had a distinctive, breezy pop style built around the three-part harmony of Hicks (lower harmony) and bandmates Allan Clarke (lead vocals) and Graham Nash (high harmony). Hicks contributed his first solo composition for the group ("When I'm Not There") to an EP release in 1964 and co-wrote a B-side ("Keep Off That Friend of Mine") with drummer Bobby Elliott that year. Hicks then joined Clarke and Nash as the group's in-house songwriting team, who from 1964 to mid-1966 wrote as "Chester Mann" and "L. Ransford" before adopting the Clarke-Hicks-Nash banner. By the mid-1960s the threesome had become responsible for writing most of their songs, including singles hits such as "Stop! Stop! Stop!", "On A Carousel", "Carrie Anne" and "King Midas in Reverse". Hicks rarely sang lead vocals on Hollies songs, but was featured on "Look Through Any Window" (1965), and sang verse leads on "Too Much Monkey Business" (1964), "Carrie Anne" (a song he began for the band in Stavanger, Norway in 1967) and "Open Up Your Eyes" (1968). Hicks took solo lead vocals on his song "Pegasus" (1967), the Clarke-Sylvester-penned "Look at Life" (1969), his "Born A Man" (1973), "Hillsborough" (1989) and Bobby Elliott's "Then, Now, Always (Dolphin Days)" (2009).
