[1] After becoming regulars at the Grand Ole Opry and scoring a string of hit singles in the late 1950s and early '60s, the Louvin Brothers broke up in 1963 due in large part to Charlie growing tired of Ira's addictions and reckless behavior.

Rolling Stone ranked the Louvin Brothers number four on its list of the 20 Greatest Duos of All Time.

When performing and drinking, Ira would sometimes become angry enough on stage to smash his mandolin when he was unable to tune it, and - when sober - glue it back together.

[7] In his New York Times review of Charlie's biography Satan Is Real, Alex Abramovich said, "Ira Louvin was a full head taller than his younger brother, played the mandolin like Bill Monroe, and sang in an impossibly high, tense, quivering tenor.

But every so often, in the middle of a song, some hidden signal flashed and the brothers switched places — with Ira swooping down from the heights, and Charlie angling upward — and even the most careful listeners would lose track of which man was carrying the lead.

His fourth wife, Anne Young, and he were on the way home from a performance in Kansas City when they came to a section of construction on Highway 70 outside of Williamsburg, Missouri, where traffic had been reduced down to one lane.

Country-rock band The Byrds recorded the Louvin-penned "The Christian Life" for their 1968 release Sweetheart of the Rodeo.

Designed by Ira Louvin, the cover features the brothers standing in a rock quarry in front of a 12-foot-tall (3.7 m) plywood rendition of the Devil as several hidden tires soaked in kerosene burn behind them as fire and brimstone.
