David Porter, one-half of the Stax songwriting team Hayes and Porter, is considered one of the most important American popular songwriters of the 20th century. His memoir, The Soul Man, details his pivotal contributions to Sam & Dave's iconic 1966 hit, "Hold On, I'm Comin." Porter also discusses his relationship with the Recording Academy and his founding of his music non-profit The Consortium MMT. The book's introduction includes an excerpt from Porter's most candid account about a bathroom visit that led to the song.
