Amy Winehouse played a polished and sober comeback show Sunday

Amy Winehouse performed a polished and sober UK comeback show on Sunday (12.06.11).

The troubled singer - who recently completed a short stint in rehab for problems with alcohol ' played seven songs including 'Rehab', 'Back to Black' and 'Valerie' as well as new tracks for a small crowd at London's 100 Club, her first show since a handful of dates in South America in January.

A source said: 'Amy was on fantastic form. She looked and sounded great. It was like one of her old performances."

Amy also entertained the audience - which included her mother Janice, aunt Jane and boyfriend Reg Traviss - with a selection of jokes.

The source added: 'She had the crowd laughing along with her gags, poking fun at herself and dad Mitch. She also threatened to flash her boobs and made a few jokes about her voluptuous look.'

Onlookers also believe her most recent rehab visit was a success as Amy didn't touch a drop of alcohol all night.

The source added to The Sun newspaper: 'Gone was the fragile, volatile and unpredictable Amy. She wasn't knocking back vodka on stage ' and she definitely hadn't stopped at the off-licence on her way to the gig.'

Amy is reportedly planning some more intimate shows in preparation for an upcoming 12 date European tour which starts in Serbia on Saturday (18.06.11).
