Marilyn Manson canceled his performance in Toronto right before he was to go on Thursday night.
Here's the announcement from the stage about the show being axed because of illness. It didn't go over well with the crowd. You can even see that the stage was set for Manson in this video. The announcement happens at 1:09 into this video.
Rob Zombie ended up doing a longer set in Manson's absence, and even threw in a cover of "Sweet Dreams," the Eurythmics song that Manson had a hit with back in the 90s. John-5 and Ginger Fish from Zombie's band used to be in Manson's band so the song is probably familiar to them.
