This video was recorded in Glastonbury in 2007.
Maybe you want to know something about this great artist. I just pasted what the wikipedia says about her. 
Below, you’ve got the lyrics of the song.
It’s interesting to know about this phenomena! 
“Amy Jade Winehouse (born 14 September 1983) is an English singer-songwriter, known for her eclectic mix of various musical genres including soul, jazz and R&B.
Winehouse’s 2003 debut album Frank did well, both commercially and critically, in her native Britain. It was nominated for the Mercury Prize. Her 2006 follow-up album Back to Black led to six Grammy Award nominations and five wins, tying the record for the most wins by a female artist in a single night and becoming the first British singer to win five Grammys,[3][4] including three of the “Big Four“: Best New Artist, Record of the Year and Song of the Year. On February 14, 2007, she won a BRIT Award for Best British Female Artist; she had also been nominated for Best British Album. She has won the Ivor Novello Award twice, among other prestigious distinctions.
Winehouse has created media buzz apart from her singing. Her distinctive style, most notably her former signature beehive hairstyle, has spawned imitators and been the muse for fashion designers, most notably Karl Lagerfeld. The singer’s struggle with drug and alcohol addiction, as well as self-destructive behaviour, have become regular tabloid news since 2007. She and her husband have also been plagued by legal troubles that have led to the cancellation of several tour dates.”
LYRICS
Mum bought you a fur
Coat when you were fifteen
You wore it to the disco,
But everyone was in jeans
But you were a rich girl,
And only having fun
Your low cut dresses,
Brought stares from everyone
Hey, little rich girl where did you go wrong?
You left for London,
When you were nineteen
Had to pull off your nice clothes,
Just living on dreams
A man in the bright lights
Took all that you own
Now he’s taken your freedom
For a fate unknown
But you were a rich girl,
Hardly having fun
Your worn out dresses,
Brought stares from everyone
Hey, little rich girl where did you go wrong?
Hey, little rich girl you’ve been away for so long
And now little rich girl,
my words are in this song
Hey, little rich girl my love for you is gone
And now little rich girl,
I know where you went wrong
At your dad’s office party
All the movies were blue
Caused him so much heart ache,
Because the screen star was you
You left for London,
When you were nineteen
Had to pull off your nice clothes,
But you were living on dreams
You were a rich girl,
And only having fun
But your worn out dresses,
Brought stares from everyone
Hey, little rich girl where did you go wrong?
Hey, little rich girl where did you go wrong?
Hey, little rich girl where did you go wrong?
