This seven inch vinyl is to be released on December 9, and is to include a previously unseen alternative vocal version of the song from the archives, along with a sheet of 'Buy Girls, Buy Boys' stickers.
5,000 copies of the vinyl are available, while 100% of the proceeds will go towards the Sarah Harding Breast Cancer Appeal, part of the Christie Charitable Fund. The charity was established following Sarah Harding's death. The singer passed away from cancer last September aged 39.
Released in December 2002, the track 'Sound Of The Underground' earned a Christmas Number 1, before spending four weeks at top spot in the chart.
