"Signed, Sealed, Delivered (I'm Yours)" is a soul song, by American musician Stevie Wonder, released in June 1970 as a single on Motown's Tamla label.

The song was arranged by Paul Riser and features an electric sitar[3] played by Eddie "Chank" Willis.

Now he has returned, making the commitment that he's back, similar to a special delivery package from the post office, "signed, sealed, delivered, I'm yours."

Wonder performed the song live on the final night of the 2008 Democratic National Convention at Invesco Field in Denver, Colorado.

The song was used in the same fashion the Clinton-Gore campaign used Fleetwood Mac's hit "Don't Stop."

This was the second single from Blue's third album, Guilty (2003), and was released in Australia two weeks before it was issued in the UK.

Janet Jackson was originally approached to cover the song with the group but could not proceed due to scheduling conflicts.
