Amy Winehouse and Blake Fielder-Civil - also known as Amy Declinehouse and Blake Fielder Not-So-Civil - have seen their share of troubles of late.
"At the end of the performance, the room erupted in applause and wild cheering," said Kevin Milburn, director of the Mercury Music Prize, awarded to the best British and Irish album of the past year.
Amid allegations of drug and alcohol abuse with Blake Fielder-Civil (whom she wed in May), Winehouse - citing exhaustion - checked into a "retreat" in Essex, England.
There also was some question over whether she would make it to the Mercury Music Prize.
But her father, Mitch, was all smiles after watching her belt out an acoustic rendition of "Love is a Losing Game" from her nominated album, Back To Black.
"She was very happy to be here. And I'm just thrilled she was here," Mitch Winehouse told the BBC. "Amy gave a brilliant performance and she looks well."
"Amy announced she would not be doing any performances for a few months but flew in from her holiday in St. Lucia especially for the occasion," Milburn said.
She didn't win the Mercury Prize (which went to the new rave group, the Klaxons) but Amy Winehouse, 23, still impressed the judges.
Truly inspirational. This just goes to show that when you don't OD and try to mutilate yourself, you can accomplish anything.
