There are a bunch that come to mind...
BTW: RUSH - 2112 is a great album, still have the LP. When I get out of work I am going to have wipe the dust off the cover and fire up the turn table listen to that front to back. My wife will probably tell me to put my headphones on since she cant stand Geddy Lee's vocals
Before the dawn - Judas Priest ... is probably the saddest in the list.
Titanic Movie Song - My heart will go on - Celine Dion ... always gets my wife into tears when leonardo dicaprio dies and sinks into the sea, the movie ends and then they show the cast as ghosts on the ship and then her flood of tears start that I believe is amplified by the song.
Judas Priest - Before the Dawn, Lyrics
Before the dawn, I hear you whisper
In your sleep "don't let the morning take him"
Outside the birds begin to call
As if to summon up my leaving
It's been a lifetime since I found someone
Since I found someone who would stay
I've waited too long, and now you're leaving
Oh please don't take it all away
It's been a lifetime since I found someone
Since I found someone who would stay
I've waited too long, and now you're leaving
Oh please don't take it all away
Before the dawn, I hear you whisper
In your sleep "don't let the morning take him"
