Jermaine Jackson's 'Smile' to hit iTunes

Michael Jackson's brother sang song at memorial

Jermaine Jackson's rendition of "Smile" sung at his brother's public memorial is coming to iTunes.

A judge granted Michael Jackson's estate a request to enter into an agreement with Apple to distribute the song on its popular music downloading service.

The agreement calls for both the audio and video of the performance to be sold. Documents immediately available didn't say how much the deal is worth.

Jermaine Jackson said the song, written by silent film star Charlie Chaplin, was Michael Jackson's favorite.
