More cancellations and postponements are ahead on Janet Jackson’s ‘Rock Witchu Tour’. On Saturday Sept. 27th Janet’s first tour cancellation came about due to “production constraints.” The following Monday the tour stop in Montreal was also cancelled after Janet began feeling sick from, what her camp is now calling, dehydration. She was then released from the hospital after an examination declared she would recover just fine. Unfortunately for ticket holders the tour stop in Montreal was still cancelled and Janet and her entourage continued on to the next venue. Now, it’s been revealed that tour stops in both Boston and Philadelphia has been cancelled also. Her reps, though, say she will resume her tour on Saturday in Greensboro, NC. Feel better soon Janet.
