NASHVILLE, TENN. • Country musician Stonewall Jackson, who sang on the Grand Ole Opry for more than 50 years and had No. 1 hits with “Waterloo” and others, died Saturday after a battle with vascular dementia. He was 89.

The Opry, the longest-running radio show in history, announced Jackson’s death in a news release.

Jackson, a guitarist, performed on the Opry beginning in 1956 and was still appearing in 2010. His real name was Stonewall, after Confederate Gen. Thomas “Stonewall” Jackson.

According to WSMV-TV, the late Porter Wagoner would introduce Stonewall on his show by saying he came to the Opry “with a heart full of love and a sack full of songs.”

“Waterloo” was a hit on the country and pop charts in 1959. His other hits, mostly in the 1960s, included “Don’t Be Angry,” “B. J. the D. J,” “Why I’m Walkin’,” “A Wound Time Can’t Erase” and “I Washed My Hands in Muddy Water.”
