It has been billed as the biggest comeback in pop history.
But thousands of Michael Jackson fans have been left disappointed even before a note has been sung.
Organisers of the star's lucrative 50-date London tour at the O2 arena, which begins in July, have cancelled the first four opening shows blaming 'technical issues'.
The dates have already been rescheduled but it now means virtually all of the 80,000 fans who had bought tickets will have to wait up to eight months to see the concerts.
Many of them live abroad and will now have to make new travel arrangements, which could cost hundreds of pounds in cancelled flights.
The show's director Kenny Ortega took the decision yesterday, with a spokesman saying a clash with Madonna, who is also performing at the venue at the beginning of July, had left Jackson with no time to rehearse at the arena.
The opening show on July 8 is now being moved to July 13. However, the second show, scheduled for July 10 will not go ahead until March 1, 2010.
