A legendary R&B and Soul singer who inspired other arguably more popular artists and ended up in the Rock and Roll Hall of Fame has passed away.

Sam Moore, of the award-winning and influential Sam & Dave duo of the 1960s, died on Friday at the age of 89, according to The Music Universe.

His death in Coral Gables, Florida, came as a result of complications following a surgery, though few other details have been revealed.

Renowned soul singer

Moore was born and raised in South Florida and discovered his love and talent for singing in church, but turned down an early opportunity to join a gospel group as he instead was more interested in the developing pop and R&B music scene.

While performing as the MC and singing at a local club in Orlando in the early 1960s, Moore met and teamed up with aspiring singer Dave Prater, and the duo was later signed by Atlantic Records in 1965 and then loaned to that company's southern division, Stax Records, where they teamed up with songwriters Isaac Hayes and Dave Porter.

That team recorded several hits over the next few years, most notably "Soul Man," which gained renewed popularity in the late 1970s and 80s when it was covered by "Saturday Night Live" comedians Dan Aykroyd and John Belushi as the Blues Brothers, and "Hold On, I'm Comin'," which has likewise been covered by several other popular artists.

Unfortunately, Sam & Dave broke up in the early 1970s and went their separate ways, but Moore's attempt to pursue a solo career was short-circuited by record company executives, and the duo reunited in the late 70s only to break up again a few years later due in part to Moore's admitted heroin addiction.

Helped inspire Springsteen

After parting ways with Prater, Moore married Joyce McRae in 1982, and she helped him finally launch a solo career by serving as his advocate and manager, as well as treatment to kick his illicit drug habit, but he never reached the same level of stardom as he had during the heyday of Sam & Dave.

However, according to the Associated Press, Moore remained incredibly popular with other artists, particularly Al Green and Bruce Springsteen, whom he joined on tour and recorded duets with on multiple occasions.

"Over on E Street, we are heartbroken to hear of the death of Sam Moore, one of America’s greatest soul voices," Springsteen said in a statement. "He was filled with stories of the halcyon days of soul music, and to the end had that edge of deep authenticity in his voice I could only wonder at."

Lawsuits and politics

The AP reported that the break up of Sam & Dave was not pleasant, as Moore sued Prater for years over Prater hiring a substitute for Moore in a duo dubbed the New Sam & Dave, and it is unclear if the two ever mended their differences before Prater died in a car accident in 1988.

Moore also unsuccessfully sued the producers of the 2008 film "Soul Men" that was loosely based on Sam & Dave's story, and in the 1990s was part of a broad lawsuit filed by multiple artists against record companies that accused those companies of cheating them out of royalties and retirement benefits they felt they were due.

In fact, Moore even testified before Congress about the issue, and also became a regular performer at the Kennedy Center in Washington D.C., and went on to sing at various events for six U.S. presidents, including Jimmy Carter, George H.W. Bush, Bill Clinton, George W. Bush, Barack Obama, and Donald Trump.

Moore is survived by his longtime wife, Joyce, along with their daughter, Michelle, and two grandchildren, Tash and Misha.
