Remembering Bobby Hebb

Has there been a more joyful song than "SUNNY" by BOBBY HEBB?
I am asking myself that question while listening to the 1966 classic upon hearing of the passing of Hebb, age 72.
I have always been fascinated by Hebb's background. He grew up in NASHVILLE -- not exactly a hotbed for black R&B.
Indeed, Hebb grew up listening to the Grand Ole Opry and served as a sideman for five years in the band of country icon Roy Acuff.
Hank Williams, Sr., reportedly befriended Hebb, telling the young musician:
"Son, when you write a song, write it as if you were writin' a letter. Just tell the truth, just like it is. If it hurts you, just tell how it hurts."
Hebb must have followed the advice. He became a great songwriter.
