AMY WINEHOUSE being described as "sober as a lamb" is not something I thought I'd hear.
But that is how a guest spoke of the troubled star at her dad's birthday bash.
After singing Happy Birthday and a few of her hits for ex cabbie MITCH at Trent Park Golf Club in north London, Wino thanked her old man for his support.
Her 13-year-old goddaughter DIONNE BROMFIELD also performed her single Mama Said.
Rather than hurling abuse and shouting at guests, Amy made small talk and signed autographs.
A source at last Friday's do said: "She was on top form. A few people wondered whether she'd behave. She didn't turn up steaming drunk and held her own all night."
I was very impressed - until I found out the party was being filmed for a documentary about Mitch to be shown on Channel 4 next year.
That's the real reason Amy avoided slugging wine like it was water.
