Dunn once said that he and Cropper were “like married people.”
“I can look at him and know what he’ll order for dinner,” he said. “When we play music together we both know where we’re going.”
Dunn received a lifetime achievement Grammy award in 2007 for his work with Booker T. and the MGs.
He is survived by his wife, June; a son, Jeff; and a grandchild, Michael, said Michael Leahy, Dunn’s agent.
