I met Luther several times through his late sister Ann who I worked with for several years at a past day job. The last meeting was unfortunately at Ann's wake ... she died from a sudden respiratory problem. (Ann was an actress herself, she played the abused wife in the acclaimed indie film "Straight out of Brooklyn") Luther was one of three children and the last surviving sibling. Saddest of all I believe Luther's mother outlived all of her children and now is burying her last.
A truly great voice and one of the hallmark R&B vocalists of our time. He will be missed.
