NEW YORK—William “Poogie” Hart, a founder of the Grammy-winning trio the Delfonics who helped write and sang a soft lead tenor on such classic “Sound of Philadelphia” ballads as “La-La (Means I Love You)” and “Didn’t I (Blow Your Mind This Time),” has died. He was 77.
His son Hadi told The New York Times Wednesday that Hart died July 14 at Temple University Hospital in Philadelphia. The cause was complications during surgery.
From the late 1960s to the mid 1970s, the Delfonics had six top 40 pop hits and more than a dozen top 20 R&B hits. With Thom Bell serving as producer and co-writer, their sound was defined by the rich orchestral arrangements and layered harmonies—Hart at times rising to a falsetto—that made Philadelphia soul as essential to the ’70s as Detroit’s Motown label had been in the previous decade.
In 1971, “Didn’t I (Blow Your Mind This Time)” brought the Delfonics a Grammy for best R&B performance by a duo or group. They were voted into the National Rhythm & Blues Hall of Fame in 2014.
Hart was a Washington native, born in 1945. He later moved to Philadelphia and began singing in groups as a teenager, and with younger brother Wilbert Hart and Randy Cain (later replaced by Major Harris) formed the precursor to the Delfonics, the Orthonics, in 1965. They soon learned of a local writer-arranger, Bell, who eventually worked not just with the Delfonics but with the Spinners and Stylistics.
The Delfonics initially broke up in the 1970s, but later toured in various combinations. Hart’s outside projects included the 2007 album “Three Tenors of Soul” with two other stars from the ’70s: Russell Thompkins Jr. of the Stylistics and Ted Mills from Blue Magic.
