"You are Everything" was done by the Stylistics, a group which was produced by Thom Bell, just as the Delfonics had been previously. The Delphonics was the result of the breakup of the Delfonics, with brothers Wilbert and William Hart going their seperate ways. Wilbert formed a group called Wil Hart and the Delphonics, whereas the others (along with the previously added member, Major Harris) remain the Delfonics. Most of this infomation was gleaned from my memory of a Delfonics greatest hits CD.
