After performances in Japan, China, Australia and New Zealand in March/April 2006, the Stones' tour took a scheduled break before proceeding to Europe. During the break Keith Richards was hospitalised in New Zealand for cranial surgery after a fall from a tree on Fiji, where he had been on holiday. The incident led to a six-week delay in launching the European leg of the tour. In June 2006 it was reported that Ronnie Wood was continuing his alcohol abuse rehabilitation programme, but this did not affect the rearranged European tour schedule. Mick Jagger's throat problems forced the cancellation of two of the 21 shows scheduled for July–September 2006. The Stones returned to North America for concerts in September 2006, and returned to Europe on 5 June 2007. By November 2006, the Bigger Bang tour had been declared the highest-grossing tour of all time.
