The Vines have cancelled their current tour due to singer Craig Nicholls deteriorating mental condition.
In a website post, the band confirmed that they were withdrawing from live and festival appearances indefinitely.
In 2004 Nicholls was diagnosed with Asperger's syndrome, an acute form of autism, after his behaviour became increasingly unpredictable.
The band wrote: “Craig Nicholls’ mental condition has deteriorated extremely rapidly over the past month to the point where he requires immediate help over an extended period of time.”
“On behalf of The Vines we would like to extend our sincerest apologies to those of you who have bought tickets to see us perform and will not get to do so” said Hamish. “We are all absolutely devastated that we've been forced to cancel all upcoming shows as there's nothing we love more than playing on stage before an enthusiastic audience. We ask for your understanding in this situation.”
