Guys, that's probably the track that Kellz recorded after Katrina along with MJ...here's Mista's quote from back in the day:

No, its Kells singing his part from Michael Jacksons Katrina Song, 'I Had/Have a Dream' that never got released. I think its from the video shoot that many artists who sang on the song did as they all have that same background. No, I've never heard the song. Its still wrapped up in legal stuff and probably be will never released offically.
