George, former front man for the 1980s pop group Culture Club, was ordered to spend five days of community service sweeping for the Sanitation Department in 2006 after he admitted to falsely reporting a burglary in his New York apartment.
The New York Post said the recording artist has promised to perform a full set of songs at the DSNY's Family Day at Floyd Bennett Field in Brooklyn Aug. 17.
About 5,000 people are expected to attend.
"He conveyed to us that he sees the difficulty in the job that Sanitation does on a daily basis -- this is just a way of him showing appreciation for New York's Strongest," DSNY representative Keith Mellis told the Post.
