Their best-known line-up included lead vocalist Brian Connolly, bassist Steve Priest, guitarist Andy Scott, and drummer Mick Tucker.
Since 1992, Scott's version has included drummer Bruce Bisland, while lead vocalist Paul Manzi, bassist Lee Small, and keyboardist/guitarist Tom Cory joined in 2019.
In 1985, Scott and Tucker organised their own version of Sweet with Paul Mario Day (previously played with Iron Maiden, More, and Wildfire) on lead vocals, Phil Lanzon of the band Grand Prix on keyboards, and Mal McNulty on bass.
Three drummers, Andy Hoyler, Bobby Andersen, and Bruce Bisland, provided short-term relief before Bodo Schopf took over.
In 1996, Mann left to take a job in television and Gibbons came back for a short time before Steve Grant of the band The Animals became the permanent keyboardist.
In 2003, Tony O'Hora (previously played with Onslaught and Praying Mantis) replaced Brown as lead vocalist.
