#4 on the UK Singles Chart, It had less chart success in the United States where it reached #61 on the Billboard Hot 100. Nevertheless, its success led to an extensive international tour from 1976-1977. Sherbet's foray into the US market began in 1977 with their album, Photoplay, retitled, Magazine; however, it failed to chart in the US. Sherbet then signed with RSO Records and changed their name to Highway, but had no US charting with their subsequent album, Highway 1 (1978). In mid-1979, the group disbanded and returned to Australia; nonetheless, Davies remained in America. Later on, in 1980, the band reformed as the Sherbs. Olivia Newton-John (1979 - 1986) In 1978, in Los Angeles, Roger Davies became the manager for Steve Kipner (ex-Steve and the Board, Tin Tin), a singer-songwriter, who had been in Australia during the 1960s. Davies also worked for Olivia Newton-John's then-manager, Lee Kramer. Kipner had co-written the track "Physical" for Tina Turner, another of Kramer's clients, who thought it "too obvious" and rejected it.

In April 2018, the Australian television bio-picture Olivia Newton-John: Hopelessly Devoted To You featured Delta Goodrem as Olivia Newton and Gyton Grantley as manager Roger Davies. Tina Turner (1980 - 2010) In 1980, Roger Davies' employer Lee Kramer became the manager of singer, Tina Turner. Turner had divorced her husband, Ike, in March 1978 and by 1979 was without a record contract. To support herself, Turner had worked on the club circuit. It was on the set of Olivia Newton-John's pre-recorded ABC TV Special “Hollywood Nights” in March 1980 that Davies first met Tina Turner, a performing guest on Olivia's show, transmitted April 14,1980. Later on, Tina invited Davies and Kramer to her performances at the Venetian Room at the famous Fairmont Hotel, San Francisco, in May, where "She
