Some of Brighton's top music labels are joining forces to help a young boy's fight against cancer.

DJs from Positive Sound System, Tru Thoughts, Catskills, Covert Records, Grin, Phonic:Hoop and ESP are playing a one-off gig tonight in aid of 14-year-old Josh James.

The Varndean School pupil, of Birch Grove Crescent, Brighton, has a rare condition called Ewing's sarcoma and has undergone months of radiotherapy, chemotherapy and even a stem cell transplant.

The cancer grows in bones or soft tissue and doctors have told Josh he could have just months to live.

Medical experts in Britain have exhausted curative treatment in the UK and have said Josh will not survive if other forms of treatment are not explored.

Tonight's event takes place at the Old Market in Hove, starting at 10pm. As well as tunes from some of the city's finest DJs, the night will feature a raffle or auction of various signed CDs, photographs and other collectable memorabilia.

The event has been organised in just a few days by business development manager Lee Edwards.

He said: "I am a dad myself and when I heard about Josh I knew I had to do something.

"It has not been just me - I've had lots of help from all sorts of people and the response has been fantastic.

"The tickets cost £10 - with all the money going to help Josh - but if people feel that is a little steep then we will accept donations at the door."

Tonight's gig is the latest charity event organised since The Argus highlighted Josh's plight at Easter.

Staff at Asda's Brighton branches in Hollingbury and at the marina held a "go blue" event yesterday to raise funds for the youngster. They have also put out buckets for donations to his appeal and are holding a small fair at the Hollingbury store on May 9 with children's rides and stalls.

Lynn Ramzi, events co-ordinator at Asda, said the store had raised about £2,500 in bucket collections.

So far more than £16,000 has been pledged to help Josh, who is on holiday in New York at the moment courtesy of the Make A Wish Foundation.

His father Simon Early, who runs an internet business in Brighton, is searching for some kind of treatment which may help prolong and improve his son's quality of life.

He has set up a web site at www.joshjames.co.uk with details of Josh's condition and information on how to donate.
