R&B singer Natalie Cole underwent kidney transplant surgery yesterday at Cedars-Sinai Medical Center in Los Angeles. The life-saving kidney came from a deceased organ donor through the regional organ procurement agency, One Legacy. The songstress has been receiving kidney dialysis three times a week since September, often at hospital locations around the world as she continued her world tour. Ms. Cole’s physicians have advised her to postpone her summer tour dates as she recuperates for the next few months. Cole’s representatives say further information about the re-scheduled dates will be available shortly.—BB
