SEARCHING "What planet are you from" Soundtrack or at least "Everytime you go away"

I am searching the song "Everytime you go away" but not from Paul Young but from "BLUE ROOM" from the movie "Planes Trains and Automobiles". I have found the special 25th Soundtrack on this board but there is a faded out version. Surely it was made from the end credits. I have search so hard for this song that I have found out a few curious things:

It might be never completely recorded
It might be from a singer called SASHA
It might be on the Soundtrack of "What planet are you from" sung by Lisa Stone

Does anybody have this Soundtrack from "What planet are you from" and can at least tell me if it is the same girl hwo sung the "Traines, Planes an Automobiles" Version?

With best regards and many thanks for every piece of halp and information
