Michael Jackson's Single Comes Together

Mariah Carey not only performed at a Hurricane Katrina telethon Friday, but the pop singer is also singing on Michael Jackson's charity single for the victims of Hurricane Katrina, his spokeswoman said on Monday.

Carey's voice will be accompanied by "Godfather of Soul" James Brown, and rappers Snoop Dogg and Jay-Z on the track. Jackson's song is tentatively titled "From the Bottom of My Heart." Other artists said to be participating include Lauryn Hill, R Kelly, Kenneth "Babyface" Edmonds, Mary J Blige and 70s soul band the O'Jays.

Also involved in the single are Lenny Kravitz, Wyclef Jean and Missy Elliott. Jackson's spokeswoman said he is 'continuing to reach out to artists who would like to work on him on this project. He humbly hopes [it] will make a tremendous difference to all individuals who have been affected by this tragedy."

Jackson, who is not a newcomer to this, co-wrote charity song "We are the World" in 1985 with Lionel Richie to help raise money for African famine relief.

The "King of Pop," is currently in the Middle East but plans to return to the US to record the song. The single will be released on 2 Seas Records, a label owned by Sheik Abdulla bin Hamad Al Khalifa of Bahrain.
