The very first thing that comes to mind is “Lesson Number Eight,” from Stephen Sondheim’s musical Sunday in the Park with George. The speaker–the musicals main character, great-great-grandson of George Seurat–is mourning the death of his grandmother (and only relative) and his own growing alienation from the things that make life worth living. It’s beautiful and sad.
’ Here it is.
Roy Orbison’s In the Real World. It’s not “she broke up with me”, but “we’re deeply in love, but there’s no way that it’s going to work out.” A very sad theme, made sadder due to some personal relevance for me.
“I’ll Be Home for Christmas” - for the utterly unforced pathos. Not a word of loss or loneliness or havin’ dun wrong, but the final lyric will always choke a sob out of me.
