Comedy music duo Tenacious D have cancelled the rest of their tour of Australia and New Zealand, a week out from when they were set to perform. The band, made up of actors Jack Black and Kyle Gass, was supposed to play in Wellington and Auckland. Jack Black has since decided it's no longer appropriate to continue the tour, after jokes made by Gass following the attempted assassination of former American president, Donald Trump. The Listener music columist and Elsewhere.co.nz's Graham Reid says music and politcs are forever intertwined.
