The Bizzy verse came from an unfinished song that is on a extremely rare promo. If I remember correctly, I believe that I heard that it was on a very early promo for Heaven's Movie, but that would cause a problem with timelines unless the vinyl was issued in late 1996/early 1997 when Confessions was first premiered on a Tennessee radio station. This is when Bizzy was doing an interview with the station and he introduced the song as being incomplete. This resulted in rumors of a 3 verse version of the song. Well, anyways, the unfinished Bizzy track was leaked on to btnhboard.com within the last 2 years. It is just Bizzy's verse with a prolonged instrumental, which connotes that the track is unfinished.
Hope this helps.
