[8] In 1982 Shepherd and fellow flatmate, Bramley, formed a side project, a bubble gum pop group, Super K,[5] to record a single "Go Go", for which Kingsmill played drums.

[9] AllMusic's Jack Rabid reviewed "Like a Curse", as being "more slam-bang rock with great rhythm from a man who has it coursing in his bones.

[9] In June Kingsmill, Masuak and Robertson all joined rock group, the Screaming Tribesmen, which was re-established by founding mainstay, Mick Medew on guitar and lead vocals.

[12] In August 1984 Kingsmill left New Christs to join the Hoodoo Gurus, a rock new wave group, for their first United States tour.

In 1997 the group announced their forthcoming disbandment, they undertook a final three-month Australian tour, which commenced in October 1997 and finished in January 1998.

In early 2003 Hoodoo Gurus reformed and in the following March they released their eighth studio album, Mach Schau, undertaking tours of Australia, Europe and the United States.

Hoodoo Gurus iconic status on the Australian rock scene was acknowledged when they were inducted into the 2007 ARIA Hall of Fame.

Though he still enjoys playing drums, Mark has completely lost his appetite for the endless travelling and the many hours of hotel room boredom.

[22] Kingsmill briefly returned to Hoodoo Gurus in March 2016, he temporarily replaced Rieth for their Day of the Green tour.

A marriage is just really hard to keep together when you're not together, but we never had a falling out or anything like that.”[29] In mid-1996 Kingsmill injured himself, two weeks into the start of Hoodoo Gurus' Blue Cave Tour; he had leapt up from his drum kit and toppled backwards.

[30][31] He tore tendons and nerves in his left arm, which required surgery before he could rejoin the group and resume their tour.
