William “Poogie” Hart, the Grammy-award-winning lead singer of the R&B band The Delfonics, has died, TMZ has learned.
His son, Hadi, tells TMZ … William was having trouble breathing so he was recently taken to Temple University Hospital in Philadelphia, where he passed away Thursday from complications during surgery.
William and his brother, Wilbert, launched the Philly-based group in the late ’60s with Randy Cain, Ritchie Daniels and Thom Bell. The group would have a major impact on the development of the Philadelphia sound, known as T.S.O.P.
