I've posted in that thread, I've read it.
There is nothing legit. The rumor all started because a touring band mate got angry because, he claims 'stapp canceled the tour due to relapsing and is now in rehab'.
A few posts later, a quote from his wife, stating he's better.
He could have very well had just been sick. You know how hard it is to sing with mucus, sore throat, and a fever of 102?
Apparently, stapp has a show on the 25th, I read in that thread.
Has it been canceled?
