“There is nothing more I can say really, I am just sorry for causing all the disappointment to people’s plans for coming to see us.
“I know people are flying from all over the world to see the shows but there is nothing I can do, so please wish me luck and send me some good vibes.
“We have to look positive on this and I will coming back as strong as before hopefully.”
