A few reasons for remembering Hank.

I Fall to Pieces
The Chair
Don't You Ever Get Tired (of Hurting Me)
Make The World Go Away
She's Got You
Ocean Front Property
Don't Touch Me
A Little Unfair
Funny Way of Laughing
It's Not Love, But It's Not Bad
Little Bitty Tear
You Comb Her Hair
Any Old Arms Won't Do

That plus his discovery of Willie Nelson.
