The more I think about it the more I actually find a reason
U have one highly controversial artist paying tribute to another highly controversial artist .
One could argue that there's no smoking gun for Michaels mess which is true . It was never proven. But sometimes perception overrides reality/facts.
This possible reason didn't hit me (no pun) until I started watching the performance footage he posted .
Not saying I agree with the decision to cancel cuz personally I wouldn't have cared but for those desperately looking for a reason or possible explanation that's something to consider IMO
They could have had second thoughts regarding the OPTICS of it all. And I stress the word "optics" cuz I swear that didn't cross my mind til I actually saw the tribute in motion .
