OK, back to the 70's: Karen Carpenter phoned this electric guitar phenom shortly after Richard and John Bettis had written "Goodbye To Love" in '72 and asked him to add a fuzz guitar solo in the middle. It thus became the first "power ballad" of the 70's, peaking at #7. They received hate mail for "selling out" to hard-rock and many adult contemporary radio stations refused to play it. He left us last year at the age of 60.
Yesterday's answer: "Mustang Sally". I'm partial to The Young Rascals' version. Sally's Mustang was a '65 when Pickett sang it but was "updated" to a '66 by The Rascals. The working title was "Mustang Mama" and was changed at Aretha Franklin's recommendation.
