Later, Wonder and Bennett performed it as a duet for Bennett's 2006 album "Duets" and the track won won the Grammy for best pop collaboration with vocals in 2007.

"What's amazing is I was able to actually sing the song with someone that I admired for so long," an emotional Wonder said of working with Bennett. "Not just because of his voice, which was incredible, but because of his love for art. His love for peace. His love for unity. His love for civil rights. Yes, I remember as a little boy him being in places where most people would not even go to stand for the right for freedom for everyone."

In conclusion, Wonder added, "Tony, I'm going to miss you forever. I love you always and God bless that God allowed us to have you and have us in this time and space in our life."
