ohhhhhhh yes Tori Amos would be a dream come true
but I kinda think that it's gonna be low-key singer/songwriters as opposed to big names like Bono/Cohen...
In fact the list that Glo posted earlier is the people who have confirmed via myspace/twitter that they have worked with Damien on the charity/duets project: the french girl Melanie, the Icelandic guy Helgi Jonsson (I did twitter him asking but he didn't reply), Carmen Rizzo, Thomas Dybdahl, Joel, Glen??, Earl Harvin?? ohhh and earlier we forgot about Joseph Karnes, member of Pedestrian, who also states in his myspace that he worked with Damien (all credit to Glo for finding this)
