Aussie power trio Wolfmother has pulled the plug on the last six days of their current world tour due to the premature arrival of a baby boy to the band's bassplayer/keyboardist, Chris Ross.

Chris received the surprising news of the impending birth yesterday. Not surprisingly he immediately headed for the airport and commenced a 23 hour trek back to his hometown of Sydney, Australia in an attempt to be at his partner's side for the newborn's arrival. While he was somewhere over Hawaii his son was welcomed into the world by the rest of his family -- nearly a month ahead of schedule.

Due to Chris' unavoidable and unexpected absence, Wolfmother has had to postpone an instore at Virgin Records in Chicago which was supposed to happen today. The performance and signing will now happen on a later date and time to be announced.

The band has also rescheduled a completely sold out concert at the Hollywood Palladium which was to happen this Thursday, September 28. This event will now happen on Tuesday, December 12 and existing tickets will remain valid. Patrons who are unable to attend on December 12 can obtain a refund from the point of purchase and any such returned tickets will be made available for resale to other people over coming weeks.

Unfortunately Wolfmother's planned appearance as part of the Viejas Concerts in the Park series near San Diego on Friday September 29 has had to be cancelled due to availability issues. Ticketholders for this show can obtain a full refund from the point of purchase: all ticketmaster outlets and the Viejas Casino gift shop. The band would like to apologize sincerely to their fans for this inconvenience and they will do everything possible to return to San Diego at some point in early 2007.

Similarly, Wolfmother will no longer be able to take part in San Francisco's Download festival on Saturday, September 30 as planned but they promise to be back in the city by the bay as part of their next US tour which will happen in late November and early December.

Meanwhile, the band will take a planned break during October to allow Chris some family time and would like to sincerely apologize to anybody who has been inconvenienced by their change of plans for this week.

In other Wolfnews, "Jackass Number 2" -- for which Wolfmother's song "Joker & The Thief" is the title track -- was the #1 grossing movie in the US over the weekend. The video for the song features the Aussie group and the Jackass crew. It's currently creating loads of online buzz and is #1 on the "Hot List" in the current edition of "Rolling Stone" magazine.

Also, last week the band was among the most nominated artists at Australia's equivalent of the Grammy Awards (the ARIA's). They have made the final five for major categories like Best Group, Album of the Year and Single of the Year. The winners will be announced on October 29 and Wolfmother is scheduled to perform at the gala ceremony.
