Whether singing or writing, he was a musical legend

As a singer, Isaac Hayes – who died Aug. 10, 2008 – achieved many of his greatest hits by interpreting songs other people had written. "Walk on By" and "The Look of Love," along with many other songs Hayes recorded, were written by Burt Bacharach and Hal David. "Let's Stay Together" was first made famous by its songwriter, Al Green. Clifton Davis's "Never Can Say Goodbye" was recorded by The Jackson 5 before Isaac Hayes took it on.

Hayes always put his mark on these songs, making them something very different from the original recordings – but anyone who didn't know better might form the mistaken idea that the singer wasn't also a songwriter himself.

Hayes may have enjoyed interpreting other writers' music, but the truth is that he was a songwriter to the core – a talented and influential one. As a writer, he helped shape the innovative soul sound coming out of Memphis in the early 1960s, and he was a driving force behind the evolution of disco and rap. He crafted perfect hit singles, but he also moved beyond pop, composing award-winning movie scores.

Hayes's most frequent songwriting customers were Stax Records stars Sam & Dave. Early in Hayes's career, he became a session musician for Stax, a gig that evolved into an influential role writing songs for a variety of the label's artists. With his compositions for Sam & Dave, he defined the duo's hit-making career. Their hottest singles were almost exclusively the creations of Hayes and his songwriting partner, David Porter:

Soul Man

When Something Is Wrong With My Baby

Hold On, I'm Comin

Hayes wrote hits for others as well, like Stax recording artist Carla Thomas, the "Queen of Memphis Soul"…

And Lou Rawls, who had a hit with "Your Good Thing (Is About to End)", originally performed by Mabel John…

Not to mention Dionne Warwick, who won a Grammy for her performance of "Déjà Vu."

Hayes may have given some of his greatest compositions to other artists, and maybe he often preferred to take on other songwriters' material when he sang himself. But there were times when his two talents came together – and when they did, the result was something very special. The proof is in his score for the movie Shaft. Its theme song, written and performed by Hayes, is one of the most enduring funk songs of the 1970s.

The now-iconic tune hit No. 1 on the Billboard Hot 100 and won both a Grammy and an Oscar, making Hayes the first African-American to win an Academy Award for music. And on top of all that, it's blisteringly cool. 

In other words: We might listen to Hayes's songs performed by others, or we might listen to Hayes himself performing someone else's songs. But in either case, we're hearing a true musical legend at work.
