Bob Wray is a studio musician and bass guitarist who moved to Muscle Shoals from Memphis after playing in Travis Wammack's touring band for several years. When the Muscle Shoals Rhythm Section (better known as The Swampers) broke with Rick Hall in 1969, Wray took a job at FAME Studios, where he played on the Osmonds' number-one single "One Bad Apple." He has also worked sessions at Muscle Shoals Sound Studio, and recorded with such musical luminaries as Clarence Carter, Ray Charles, George Jones, and Willie Nelson.
