The New Orleans Jazz & Heritage Festival has announced that legendary singer Aretha Franklin, who was slotted to play the two-weekend fest, has withdrawn from the lineup on doctors orders and will be replaced by Rod Stewart.

Stewart will take Franklin’s place at her scheduled spot on Saturday, April 28, during Jazz Fest’s first weekend. Festival organizers relayed a statement from Franklin’s management that reads, “Aretha Franklin has been ordered by her doctor to stay off the road and rest completely for at least the next two months. She is extremely disappointed she cannot perform at this year’s New Orleans Jazz & Heritage Festival as she had expected and hoped to.”
