Sky News quoted from a statement issued on behalf of the Sugababes: "Following the recent and well documented change of line-up to Sugababes, there are a number of legal issues to be finalised by all parties in order that the band can move forward.
"Sadly, whilst these negotiations are approaching completion, it will not be possible for the band to finalise its business affairs prior to Thursday's event." Band members, Jade Ewen, Heidi Range and Amelle Berrabah are now planning a new gig, the proceeds of which will go to the Royal Blind Society, a charity chosen by the Scottish Royal Variety.
Ewen said: "This is such a disappointment to all of us because not only were we looking forward to this being our very first gig together, but my dad happens to be blind and my mum is partially sighted, and I know first-hand the great work the charity does for families like mine. That's why Heidi, Amelle and I have agreed to put on our own gig to support this massively worthwhile cause."
The band"s manager Mark Hargreaves said: "This was indeed an unavoidable decision of a contractual nature but I am delighted to confirm that all other band engagements are due to resume next week when it will be business as usual for Sugababes."
