The fan club have just released some of the best seats for Madison Square Gardens on Sun 15th June.  This has been sold out for months, so move very fast if you want to grab these now!

Also, at the start of the Canadian leg the promoter was able to release side tickets for the show once the stage had been positioned. As this situation is likely to be repeated at the other Canadian shows, if you need tickets, its worth checking with the local box office for news of any production releases.
