The Millennium Stadium gig is off for now
The One Earth environmental awareness concert due to take place at the Millennium Stadium later this month has been postponed.
Organisers Climate Change Now said the event would take place later in the year at the same venue but did not say why it had been postponed.
Those who have already brought tickets for the concert can claim refunds.
The event was to have been televised worldwide as part of a global campaign by Climate Change Now, an environmental organisation.
All profits from the concert were to have been donated to the UK charity One.
Organisers of the event said they were trying to negotiate a new date to accommodate bands who had already pledged their support and to attract bands who were unable to perform on the original date.
Michael Mathres of Climate Change Now told the BBC: “We apologise wholeheartedly for any inconvenience caused by the change of date.
“But we can assure those who have already purchased tickets that the event will still take place at the Millennium Stadium.”
