Surfing rocker Jack Johnson is set to end his year-long hiatus by headlining the Sydney, Australia leg of Live Earth concerts this summer. The singer/songwriter will join reformed rockers Midnight Oil, Crowded House and Silverchair at the July 7th concert, held in conjunction with similar events in London, New Jersey, Rio de Janeiro and Tokyo.

Johnson, a well-known eco warrior, admits agreeing to take part in Live Earth wasn't a problem but deciding which of the concerts to play was. The Hawaii-based star explains, "New Jersey and Australia are about the same distance for me, but Australia's waves are a lot better, so that made the decision easy."

Madonna and Genesis will co-headline the London concert at Wembley Stadium, while The Police will perform at Giants Stadium in New Jersey.
