The late soul singer's father appeared far from impressed when he discovered Beyonce had teamed up with Andre 3000 on a cover of Amy's classic 'Back to Black' track for Baz Luhrmann's movie 'The Great Gatsby'.
Mitch took to Twitter to voice his scepticism about the project - which came about because Beyonce's husband Jay-Z is executive producing the opulent drama's soundtrack - and to suggest the superstar would be better served donating a hefty sum to the homelessness charity he set up in Amy's name instead.
He tweeted: ''First I have heard about Beyonce and Back to Black. Sounds like some of you don't like the idea.
''I don't know this but what if Beyonce gave £100,000 to foundation. Do you know how many kids that would help? Just putting it out there!
''Let me repeat. This is the first I have heard of Beyonce doing Amys song. (sic)''
This isn't the first time Mitch has called on the super-rich to donate to the charity in a meaningful way. Last month he made at jibe at New York City's Mayor Bloomberg during a gala for The Amy Winehouse Foundation.
He sneered: ''That's a wonderful dedication. Would've been better if you sent $10 million, but you know a nice little thing in a plaque is very much appreciated.''
The non-profit organisation - set up after Amy's untimely death aged 27 in July 2011 - aims to support homeless young people and individuals with substance abuse problems.
