He reveals the source of those vocals in an interview: "16) How did you come up with the track, Heavenly Body? I remember buying this track by a group called ?The Escofferys? and it had an accapella on it that was really nice. I used to love making those tunes that would appeal to the ladies, a bit of rough with the smooth. I used to love fusing Rare Groove and Ragga in my recordings as it would have a wider appeal, and vocals was one of those things that people would come to expect from me. After lifting the ?heaven must have sent your love? sample I needed something raw to give it a contrast." http://www.planetdnb.com/dnb_interviews1791.php I think it's this one: http://www.discogs.com/release/1153173
