Sam Moore, one-half of the Grammy-winning R&B duo Sam & Dave behind '60s hit “Soul Man,” died this morning in Coral Gables, Fla. at the age of 89.

Once called “the greatest of all soul duos," he and late musical partner Dave Prater were inducted into the Rock and Roll Hall of Fame in 1992.

Mr. Moore and Dave Prater stormed the R&B and pop charts with indelible hits like “Soul Man” and “Hold On, I’m Comin’.”
