The Most Beautiful Song of The RnR era?


I'm about to spend a week with my father in law, who loves music but insists that nothing of interest (that is, beautiful) has been produced since WWII. In order to get a little music in, I thought I'd burn a compilation cd that might not offend his sensibilities too deeply. "God Only Knows", "Hello, It's Me", "Truly, Madly, Deeply", "Something", and "Bee's Wing" are in. Many others are under conssideration. Your additional suggestions would be appreciated.

Fleetwood Mac- Landslide

Bruce Springsteen- Two Faces Have I

U2- One

Weezer- Island in the Sun

Dave Mason- Sad and Deep as You

Elvis Costello- Every Day I Write the Book

Graham Nash- Simple Man

Neil Young- Harvest Moon
Just to name a few:
"White Bird" by It's a Beautiful Day
"Yesterday" by the Beatles
"Darling Be Home Soon" by The Lovin' Spoonful
"Candles in the Rain" by Melanie
"Dust in the Wind" by Kansas
"Love Alive" by Heart
"Free Man in Paris" by Joni Mitchell
"Winter" by Tori Amos
I would not call it the "most beautiful song of the RnR era" but the running list ought to include "Killing Me Softly" by Roberta Flack.
