Singer Bobby "Blue" Bland has died at the age of 83, his son said Monday.

Bland's son Rodd told CNN that failing health had forced his dad off the stage earlier this year. "He had a hole in his stomach that had become tumorous, and it was emptying into his bloodstream."

He said Bland passed away from natural causes at his home in Germantown, Tennessee. "He was in my arms," his son said. "But I'm not going to lie. I could have used at least 20 more years."

A website in Bland's name credits the singer with being "one of the main creators of the modern soul-blues sound."

"He never b**ched about not getting his due," said his son, who formerly was a drummer in his father's band. "When I took him to Beale Street for ribs and catfish, fans would come up to him. He was always courteous, polite and kind. And humble. That's what I admired."
