An old home video of a 14-year-old Amy Winehouse shows how spectacular her singing voice was from the very beginning.

Footage of a teenage Amy Winehouse from Southgate, north London shows the future star singing ‘Happy Birthday’ to her friends as they lark around with a camera.

The video shows four girls saying they are “the only ones left” at the end of a 14th birthday party and introducing themselves on camera, before they all start singing to birthday girl, named as Lauren Gilbert.

The video then pans to Amy Winehouse, who stands up and blasts the final lines of ‘Happy Birthday’ in an incredibly powerful voice, one that would become so distinctive across the world in just a few years time.

The fascinating home video was first shown in Amy, a 2015 documentary charting the life and tragic death of the singer that was released to critical acclaim.

“It’s a very complicated and tender movie. It tackles lots of things about family and media, fame, addiction, but most importantly, it captures the very heart of what she was about, which is an amazing person and a true musical genius.”

“I couldn’t believe she had that,” Alex told The Guardian.

“I think it shows that it doesn’t matter what happens in life, how famous you become, regardless of who you are, you’re always from somewhere,” he explained. “No matter what you do, you can’t forget that because it makes you who you are. And she never forgot.”
