To CHRIS- I remember the ad line for reincarnation and it was not I don't want to run anymore. that line would indicate the film MARK R, Y AND I are thinking about. That girl does not look like JENNIFER O NEIL, more likely BARBARA HERSHEY. The film we are thinking about was release by COLUMBIA in 71. It pretty much came and went, but got some good syndication exposure on TV in the 70's LIKE WNEW-TV- channel-5 in New York.
EVERYONE IS RIGHT- the music is both RANDY NEWMAN AND DAVID GRUSIN. RANDY NEWMAN wrote the main theme and song LET ME GO, DAVID GRUSIN did the score which includes a love theme. Both pieces from both composers can be heard on you tube. Check it out , nice music.
