It's so sad to see anyone in that terrible of a state. Not a fan of her music, but I hope she can clean up her act before she kills herself.

What a fail.. First, girl fans were booing at her.. Second, she sang jibberish and leave all her fans singing for her..

back to crack!

What do you expect? She's not fit to perform yet. As a fan, I'm hoping she gets help and she makes a triumphant return or stay out of the limelight for a while. Whatever suits her best.

whitney houstons “concerts” were worse.

i wonder how the backup singers feel

Jeeze, get this girl help.

meth is one helluva drug

Her dad needs to 5150 her ass.

Cracked. Out.

Total F*ing rockstar. That's how its done Amy. Johnny Cash and Jim Morrison used to do this stuff all the time and they're freaking legends.  You'll come back strong!!

I won't even watch the video. I'm too big of a fan to see her at her worst.

Beyond sad

I missed her heroin crazy!

I was expecting her to start peeling off her skin or something the way she was looking at her elbow.

I just feel bad for the backup dancer. I mean you can't back that up, there's no note to harmonize to. Stick a fork in this one folks, she's beyond recovery.

This is like really sad, she actually used to be beautiful and I do like her voice (not anymore of course).

Is this in English…?

Such a phenomenal waste of ability. Sad.

The real story here is that people actually went to an Amy Winehouse concert in 2011.
