Unlike Sun and Stax, and even Blue Note for Jazz, at Muscle Shoals, whether the original Fame Studio or the Jerry Wexler - Atlantic Records steal-way of the Swampers from FAME for Muscle Shoals Sound Studios (memo: never get in bed with Jerry Wexler; guess Rick Hall hadn't paid attention to what happened with Stax) -- there were no women involved at FAME or Muscles Shoals. It was a boys club all the way around.
No wonder that mess happened with Aretha -- those guys didn't know how to treat women.
No wonder the Stones recorded there.
Or that it was the birthplace of we-wave-stars-and-bars Country Rock (the Allmans).
