Rick Hall, who created the Muscle Shoals sound, passed on. Roger Hawkins was the house drummer. So many huge hits from unknown black artists in the 60s in Alabama...Wilson Pickett, Aretha, Rod Stewart (Tonight's the Night), Seger (Old Time Rock and Roll), Simon and Garfunkel...
https://en.wikipedia.org/wiki/Roger_Hawkins_(drummer)http://www.songfacts.com/detail.php?id=2609The lead guitar player on this was not a Muscle Shoals Rhythm Section player. It was Forrest McDonald, a young man just passing through who happened to stop in the studio that day. When we spoke with David Hood, he told us the story: "He happened to come in the parking lot in his mother and daddy's car with them, and Jimmy was out on the back porch. I believe his first name was Howie, but he probably goes by another name. But anyway, that's very true. He came into the parking lot one afternoon and Jimmy was out on the back porch. And he says, 'Well, I'm a guitar player and I'm wanting to learn how to play on recording sessions. And I think I'm good.' He says, 'Well, got your guitar with you?' He says, 'Yeah.' Jimmy says, 'Well, come on in.' And they put him on the track. His mother and daddy never even got out of the car. They sat in the car in the parking lot with the air conditioning running. And they put him on the track playing guitar and it's on the record, it stayed on there. It was a good enough part that they kept it on there."
