Virtually unknown outside of Australia, Sherbert were big pop stars in their home market in the 1970's. Between 1973 and 1977, the band had ten top 10 hits and two #1s. However, their clean-cut, teeny-booper image did not last, and by the late 1970s, their popularity had declined. In response, the band released a record under the Highway name and then briefly broke up only to re-form as The Sherbs.
The Sherbs released two LPs in an attempt to restart their career by tapping into the emerging New Wave movement (think: Split Enz). Unfortunately, they did not find much in the way of success -- Australian audiences in particular seemed to go out of their way to not buy the records. The band finally broke up in 1984.
"I Have the Skill" was from from The Sherbs 1980 debut album, (creatively called The Skill). It was the band's only charting single, reaching #61 on the Billboard charts. The early performance video is not terribly noteworthy, with the possible exception of Daryl Braithwaite's perspiration (he is the lead singer, btw).
Note that ERV also featured The Sherbs video for "We Ride Tonight" in honor of Halloween 2012.
Cool trivia fact: Daryl Braithwaite would go on to have a successful solo career in Australia from the late 1980's through the early 1990's.
