The highly improvisational "Sister Ray," which riffed on black leather, sunglasses, noise and more noise, was done in one take by the Velvet Underground, who agreed ahead of time that, good or bad, they would live with the results. While the recorded version was 17 minutes long, the band was known for stretching it to twice that length in a live setting. Andy Warhol didn't produce the song, but he did have input on "Sister Ray." According to Reed, "When we were making the second record, [Warhol] said, 'Now you gotta make sure that you do the 'sucking on my ding dong song.'"
Aretha Franklin went into Atlantic Records' New York studio on Valentine’s Day, 1967, with the idea to remake the then-two-year-old Otis Redding track “Respect.” Producer Jerry Wexler brought in musicians from Fame Studios in Muscle Shoals, Alabama, and celebrated sax man King Curtis; Aretha’s sisters, Carolyn and Erma, provided backing vocals; Arif Mardin arranged and Tom Dowd engineered. Mardin summed up the feeling of the day: “I have been in many studios in my life, but there was never a day like that. It was like a festival. Everything worked just right.” Aretha and Carolyn Franklin came up with the idea to spell out the word respect in the bridge and to add the “sock it to me” chant at the end. “I fell off my chair when I heard that!” said Dowd. To clarify, that often-misunderstood line is “R-E-S-P-E-C-T, take care, T.C.B.,” where T.C.B. stands for “take care of business.”
