Zoe Mace's family is waiting anxiously to hear if the 10-year-old singer has been placed in the music charts less than a week after releasing her second CD.

The Cokethorpe schoolgirl only needs to sell 10,000 copies of Songs for My Sister to reach the number one position in the UK Light Entertainment Chart, which will be announced on June 12.

Her mother, Linda, said the album, which is raising money for the Downs Syndrome Association, had already shown signs of being a success after a whirlwind of media interest.

She said: "Proper Music Distribution, the company which is distributing the CD to shops across the UK has already sold 7,000 copies to stores.

"We've been told that it sold out in York, and it's being featured on all the major stores' websites. But Zo is very matter-of-fact about it all!"

Zo, who returned to school after the launch, decided to continue recording Songs for My Sister at Easter, despite the death of her little sister Jodie, to whom the album is dedicated.

The four-year-old was born with Downs syndrome and holes in her heart, but failed to recover from major cardiac surgery at the John Radcliffe Hospital, Headington, in March.

It was her care at the JR which inspired Zo to last year record her first album Little Ray of Light, which was sold throughout Oxfordshire and raised £27,000 for the Oxford Children's Hospital Campaign. The new CD, a 12-track mix of folk, jazz, classical and original songs written by Cokethorpe School music director Ben Heaney, is being sold nationwide in WHSmith, Virgin and HMV.
