Celebs Support Children In Need Of Adoption

On the 28 January, over 5,000 of the UK's most talented young singers, including performers from X-Factor & Britain's Got Talent are due to perform at the O2 Arena in London, in a musical journey through the story of adoption. Narrators include celebrities with personal experience of adoption, including: Rick Wakeman, Sinitta, Nicky Campbell and James O'Brien.

The Voice in a Million project, in association with the British Association for Adoption and Fostering (BAAF), aims to raise awareness for the need for adoptive parents in the UK.

Piers Morgan says: 'Every child needs a loving family. If Voice in a Million results in just one child finding a new mum and dad and a secure family environment, it will be worth its weight in gold. It's projects like this that can really make a difference'. Sir Elton John says of the event: 'I fully support the 'Voice in a Million' project; and wish you the very best of luck for your event'.

The 02 concert is the first of many planned worldwide in which one-million children will air their voices as one. One-million voices singing in harmony, throughout the world, bringing awareness of all the children who have suffered loss, abuse, neglect or abandonment.
