I got to visit that studio in 1985. It was so cool and the hallway with all the gold & platinum records freaked out my 15 year old self. My gf at the time, she grew up in Muscle Shoals & her grandfather grew up with Roger Hawkins Sr. So Mr Hawkins gave us a tour. Roger Jr was not there but seeing the records he played on up on the wall. I just remember looking at Kodachrome. Btw, the one mic recording is great. Most of the original rnr music like Elvis/Bill Haley/Fats Domino was tracked that way. You had to be good & get it fast.
