At the end of last month Aerosmith had to cancel shows while Steven Tyler dealt with an undisclosed medical issue.
Tyler wrote an apology to fans saying he wasn't dealing with a life-threatening condition and that he needed to deal the problem right away.
Reports came out that he had suffered a seizure but Tyler said that was not true.
"It breaks my heart to have left this tour early ... the band has never played better ... just watch the 100,000 people at Rock In Rio. I give you all an A+ for creative speculations, but I certainly did not have a heart attack or a seizure (unless Joe Perry is takin’ a rippin’ lead). Sorry to have cut the tour short, but I had to have a procedure that only my doc in the States could perform."
Hopefully they will resume their tour again after performing a three song set as part of a benefit at Rogers Arena in Vancouver on October 21.
