Aretha Franklin’s 'Respect' is one of the most powerful anthems in music history, but it was originally written and recorded by Otis Redding. In Redding's version, the song is a man’s plea for respect from his woman when he comes home from work. Franklin flipped the perspective, turning it into a demand for dignity and a civil rights/feminist landmark. She added the famous 'R-E-S-P-E-C-T' spelling and the 'Sock it to me' backup vocals, which were ideas from her sisters, Erma and Carolyn. The song reached number one and won two Grammys. Otis Redding famously joked at the Monterey Pop Festival that the song 'belonged to that girl now,' acknowledging that her version had become the definitive one.
