Check out the article in the latest issue of Smithsonian magazine, July/August 2018, "Impersonating the Queen of Soul" by Jeff Maysh.
I remember this story well when it happened here in Florida back in
1969. And it was amazing then! We couldn't believe Aretha Franklin would be playing some of the small venues, some almost dives, that she was being
booked. Even radio spots and posters [[showing the real Aretha) were advertising her appearances. It's like a 7 page article!
