Well... it's who he left the club with that's causing a stir:
Father of the late Amy Winehouse, Mitch Winehouse was snapped at the Flordita in London.
The singer crooned in front of a crowd and was dressed in dapper form for his performance.
We see where Amy got her talent!
Mitch is a Sinatra fan and the mood of the bar seems to go along with the big band vibe.
Check out the pictures of Mitch serenading the London audience!
