It was in the disco era of the mid-1970s that Hot Chocolate became a big success. A combination of high production standards, the growing confidence of the main songwriting team of Wilson and Brown, and tight vocal harmonies enabled them to secure further big hits such as "You Sexy Thing" and "Every 1's a Winner", which were also US hits, peaking at No. 3 (1976) and No. 6 (1979), respectively. After Wilson's departure for a solo career, that included a 1976 album "I Like Your Style", Brown assumed all songwriting duties. Wilson was initially replaced by Brian Satterwhite; before Satterwhite departed the band and Olive switched to bass as his primary instrument.
