Jack Black announces on Instagram that he’s canceled Tenacious D’s tour. The ‘School of Rock’ star says he was ‘blindsided’ on stage during Sunday’s concert in Australia, after bandmate Kyle Gass said, ‘Don’t miss Trump next time.’ A reference to the assassination attempt on the former president at a Pennsylvania rally over the weekend. Black’s longtime friend and music partner also shared a statement on Tuesday, telling their fans, ‘The line I improvised onstage Sunday night in Sydney was highly inappropriate, dangerous and a terrible mistake.’
