This will knock you for six - James Percell Everything Must Change, Homeless man.

He wears a cardboard sign that reads: 'Will sing or vocal train you for food or small donation.'

In the video, Kenneth Williams speaks to the camera and explains how he discovered Mr Percell.

'I was out here in the Bronx, visiting my family, and I ran into this homeless brother,' he says passionately to the camera.

'His voice is incredible. You heard about Ted Williams, this guy's name is James Percell.'

Mr Williams asks a surprised Mr Percell how someone so talented can end up on the streets.

'Well a lot of this and that. I lived for music,' he says. 'I lived on the edge for music. I guess I was selfish.'

He says that he's been homeless for a few years, earning spare change with his songs.

'I've been homeless about five years,' he says. 'I neglected everything for the love of music.'

He told the New York Post that he spent three years behind bars for robbery and assault and currently stays with the mother of his seven children from time to time, who range in age from 5-28 years old.

In an attempt to try and launch his career, he said he's tried out for The Voice and the X-Factor singing competitions.

'The judge... said, "How can we contact you?" [But] once he knew I was homeless, his persona changed. He said, "Well, listen, maybe next time,"' he told the Post.

He has a MySpace page and Facebook fan page that list several of his other tracks with titles like Love 4 a Gangster, Control, Shower and It's Your Body.

The song featured in the video, Everything Must Change, was written for Michael Jackson.

'Once I heard him sing, I just heard platinum,' Mr Williams said to the MailOnline. He hopes that the video will help the world 'know his story and life struggle to make it as a singer/songwriter.'

The lyrics speak of a world with little hope that must be altered.

In the video, he belts his heart out for the camera for several minutes and a car rolls up.

When he approaches it, the driver rolls up her window.

'The world has no humility no mercy,' he says.

'They see you starving or whatever you going through and everybody's just passing by. They just cant lend a hand.'

He's hoping that social media can give him a fighting chance to finally make his dream come true, like it did for Ted Williams.

Mr Williams, 54, became a media sensation when he was filmed panhandling in Columbus, Ohio, and thanks to a few million hits, he was able to turn his life around and reunite with his family.

'We have 1.4 million views on YouTube so far but we're still looking for our big break,' Mr Williams told the MailOnline.

'We got a contact with a big producer in Los Angeles that we're working with. People want to do documentaries on him.'

With a bit of luck and a lot of page views, Mr Percell's lyrics just might come true.

'Things are going to change someday soon,' he croons.
