I'm so thrilled to know they have an Airstream. I'm not sure if it is at the original MS studio or not, but either way it is great. We own a studio in Nashville and a pro-audio company. We have purchased many pieces from the famous Muscle Shoals studio. Some wonderful historic pieces. Such great mojo there! Wild Horses by the Rolling Stones was written by Mic and Kieth in the tiny bathroom of the studio! Aretha, Stones, Willie, Paul Simon, Rod Stewart, too many names to even mention have cut hit records there. Just sharing a fun fact.
