A Kingston-based firm is going head-to-head with the X Factor winner while doing its bit for charity this Christmas by releasing a special single.

Employees at mobile phone company Genuine Solutions Group Ltd has recorded a version of Band Aid classic 'Do They Know It's Christmas?' and hopes to top the fund-raising charts as well as the pop charts.

Proceeds from every download of the song being donated to the Rainbow Trust, which helps support families of children battling life-threatening or terminal illness.

The firm hopes that, with the help of family, friends, social media and anyone with a sense of humour, the single can top 10,000 downloads in one week – a number which generally guarantees a slot in the UK charts.

Head of Group Marketing at Genuine Solutions, Danny Lack, said: "This Christmas, we wanted to put a promotion together that would not only be fun for our customers, but fun for our staff and provide an end of the year fundraising opportunity.

"We hope we can raise a big sum of cash for Rainbow and want to get as much publicity as possible for the charity and its valuable work. It would be absolutely amazing to track the song’s progress through the UK charts, highlighting and helping Rainbow as it goes - but we need everyone’s help to achieve this.

"It is a small thing that will make a big difference to the families Rainbow supports and we are asking everyone to download this video for fun and fundraising."

The video is available to download from today and, as it stands, will be on sale on itunes until December 18.
