The 11-time Grammy Award winner has made commercials that will air ahead of P&G coupon inserts featuring Legend on the cover that will be in Sunday newspapers July 31.
The promotion by the Cincinnati-based consumer products giant will include Facebook and other online efforts to raise money for the Communities in Schools organization's efforts to keep children in school.
As part of his broad support of education reform, Legend has focused much of his charitable work on improving education, which he calls "a civil rights issue for our time."
He says making sure that every child has access to a quality education is key. The Springfield, Ohio, native is concerned about what he calls politically motivated efforts to weaken teachers' unions in Ohio and other states.
