George Michael has unveiled Stevie Wonder's 'You and I' as the song he has covered for the Prince William and Kate Middleton Royal Wedding.

Michael has been teasing fans all week via his twitter posts about the song and only hinted that it was an obscure song from the 70s by one of his favourite artists.

At this official website it states, As a gift to everyone, in celebration of The Royal Wedding of Prince William of Wales and Catherine Middleton, George Michael has released this very special version of Stevie Wonder's "You and I."

George Michael 'You and I' is now available as a free download at George's website but he encourages fans to make a donation to the Prince William & Catherine Middleton Charitable Gift Fund after they download the song.

'You and I' was originally released by Stevie Wonder on his 1972 album 'Talking Book'. It was the same album that featured his classics 'You Are The Sunshine Of My Life' and 'Superstition'.
