The 50-year-old held a press conference yesterday in London and arrived an hour and half late.
Tickets go on sale on 13 March, but the presale registration website, MichaelJacksonLive.com, is already struggling to cope after receiving 16,000 requests per second, according to a spokesman for AEG Live, which is promoting the concerts.
