The Most Beautiful Song of The RnR era?

Do you self a favor and buy your father in law "Secret Heart" by Curtis Stigers and give it to him. He will love it, he will scratch his head and say gee I thought they didn't write em like that anymore.Then give him "Standard Time" by Steve Tyrell and he will say how come I've never heard of this guy before. And yes he will love it too. Trust me. The songs are the stuff he used to listen too but updated like Irving Berlin ,Fats Waller, etc etc.

Don't forget Van Morrison. Too many to mention but you can't go wrong with what ever you choose. Then there's Rubber Soul...
Er..how you define the RnR era?

I'm sure I missed a couple hundred or so but there is my take on beautiful songs of The RnR era. Guess this generation or so since doubya, doubya 2 hasn't accomplished much...(just kidding) Happy Listening!

Thanks for the ideas, everyone.

To clarify:
R'n'R era really means music made by rock musicians. Since the idea is to debunk his notion that rock musicians haven't made any beautiful music, I thought a well selected compilation might broaden my father in law's view of "r'n'r" songwriters while allowing me to get in some contemporary music listening time during the family vacation. Though some responses went a different way (my original post was worded more generally), I'll look forward to exploring some of those suggestions for my own benefit.

Beeswing did refer to the Richard Thompson song. If my FIL is ok with RT's voice, I'm betting he'll like the song.
