I could nominate a bunch of Todd Rundgren tunes as most beautiful but I've narrowed it down to two: Bag Lady from the Hermit of Mink Hollow album and Compassion from the Healing album. Beuatiful, haunting melodies and touching lyrics.
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.
