This was not in a movie I don't think but I loved it back in '67 when I lived in Detroit working on a degree at Wayne State Univ.
Ed Ames was a terrific singer and also an actor - one of my favorites. Every time I hear this I think of those single days of studying, dating, hitting the night scenes in Detroit, go-go girls, etc. (I repented of my wild days there, and left after the race riot of fall, '67.)

Here's why I love this song, if you'll allow me. It is biblical. We have to often walk through valleys that are seldom fruitful, and so this journey whose end is death itself must be walked through. However, we do not have to be lost in this valley for we have a God who has promised to guide us through to safety on the mountain on the other side. Our Shepherd has told us that there is no sting in death, nothing to fear, for He has defeated it. The sheep of Christ, when they come to this valley, have a table set before them, the enemy will be rebuked, and our Shepherd will guide them with his rod, and sustain them with his staff. The Lord's people feast at his table, upon the provisions of his love. Satan and wicked men are not able to destroy their comforts, while they are anointed with the Holy Spirit, and drink of the cup of salvation which is ever full. Past experience teaches believers to trust that the goodness and mercy of God will follow them all the days of their lives, and their cups will ever be full. That’s His promise, and you can depend on it..
