Sherbet (band)

Context: The breakup did not last long. In 1980, Sherbet reconvened as The Sherbs with exactly the same personnel they had before the split: Braithwaite, Harvey, Mitchell, Porter and Sandow. The new renamed iteration of the group also changed their approach, as they now featured a somewhat modified progressive new wave sound. This version of the band had some minor success in America, but their almost complete lack of chart action in Australia was in stark contrast to their 1970s heyday.  The Sherbs' first album The Skill was released in October 1980 and reached the top half of the Billboard 200. It was the first album by the group - under any of their names - to chart in the US. An accompanying single, "I Have the Skill", became the band's second US pop chart hit at No. 61. The Sherbs also appeared on the inaugural AOR-oriented Rock Tracks chart issued by Billboard in March 1981: "I Have the Skill" debuted at No. 45. The track peaked at No. 14 - the band's highest position on any US chart,  and The Sherbs also received airplay on US album-oriented rock (AOR) radio stations with "No Turning Back". However, none of the singles from The Skill reached the Australian Kent Music Report top 100, a huge comedown for a band that had been major charting artists in Australia only two years earlier.  The Sherbs's second album, Defying Gravity, followed in 1981, but failed to produce a single that charted in the either the US or Australian top 100. The band did, however, chart on Billboard's Rock Tracks Chart with the album cut "We Ride Tonight" peaking at No. 26 in 1982. The track's mild AOR success was not enough to ignite album sales in the US, though, and Defying Gravity only reached No. 202 on the album charts. A mini-album, Shaping Up, appeared in 1982. It was critically well received and spawned two minor hits in Australia, but the US issue missed the chart completely. The Sherbs were now in a position where the US listening public were largely indifferent to their releases, and - despite their newer, more contemporary sound - the Australian audience had seemingly written them off as a relic of the 1970s. Porter has said that he found this especially frustrating, as he felt The Sherbs were actually writing and performing better material during this era than in their 1970s heyday.  James left The Sherbs at the end of 1982 to be replaced by Tony Leigh (Harry Young and Sabbath, Gillian Eastoe Band) on guitar. In late 1983, the group announced their decision to disband in 1984, they reverted to the Sherbet name and undertook a successful farewell tour of Australia and a final single, "Tonight Will Last Forever". Shakespeare returned to co-write and appear on the final single. Both Shakespeare and James rejoined Sherbet on the final tour. Following the group's break-up, Braithwaite continued his solo career in Australia, and Porter and Shakespeare each became successful record producers. In 1990 Sherbet were inducted into the ARIA Hall of Fame alongside classical composer and pianist, Percy Grainger. CANNOTANSWER
