It's not Mishon Impossible but this 17-year-old could be Sussex's answer to Robbie Williams.

Already James Mishon has been referred to as the Boy Sinatra and his father and grandfather are keeping a close eye on his talent.

As a schoolboy, he has done impersonations of his favourite singers and his skills have also seen him sing in New York and Los Angeles.

His first national TV appearance is on BBC1's Blue Peter on February 5 and he will sing at the London Palladium on April 22 at a concert to celebrate the 125th anniversary of the Green Room Club in London, organised by his grandad.

James, of Hove, is the son of estate agent Glenn Mishon of Mishon Mackay, one of the best-known estate agents in Sussex.

And with his grandfather Barry Mishon an impresario, who has put on several successful London shows, the base is there for him to take off.

He has dropped the name Mishon and is using his first two Christian names for his career. With his CD, James Alexander at Seventeen, he is following in his father's footsteps.

In the Seventies Glenn released a cover version of Herman Hermits' There's A Kind Of Hush.

Glenn eventually took over his father's estate agency business in Haywards Heath and then formed a partnership with Alex Mackay.

Barry concentrated on being an impresario, and is now guiding James's career.

Glenn said: "I just wanted to release a record. Now I am reliving my brief pop career through my son, and he's far better."

James said: "We had a jazz band at St Bedes School, Eastbourne, and it started from there. I would do impersonations of my favourite singers - Neil Diamond, Frank Sinatra and Ronan Keating.

"Frank Sinatra is my hero, and when someone once referred to me as the Boy Sinatra, it was a terrific complement."

James's repertoire includes easy listening classics Love on the Rocks, My Favourite Things, Stardust, and Can You Feel the Love Tonight..

He said: "I am going to concentrate on the over-30s market, but if six-year-olds to 29-year-olds like my music as well then that is a bonus.

"My family is not pushing me, they are just being highly supportive."

Barry said: "At the end of the day it is his talent which will tell. With my experience in the business, I would not encourage him unless I knew he had got what it takes."
