On cheeseman's catalogue, "Loving You" by Jusy & Shara from Hi-Site was made by "Sara" (which is Sara Righetto). But I noticed there is another singer ! Listen that video from 7:18-7:28 to 7:41-7:46
There is also Sara Righetto after her https://www.youtube.com/watch?v=f60eOT9ysfE
The other vocalist on that song is probably "Francie" who did "Bad Bad Boy" for Delta
