William Hart, the lead singer and songwriter for the R&B group the Delfonics, died on Thursday at the age of 77
He died Thursday at a Philadelphia hospital following complications from surgery.
Hart’s death was confirmed by his brother and co-founding bandmate Wilbert Hart, who wrote on Facebook, “R I P. My. Brother. William. Poogie. Delfonic. Hart”
Hart's voice can be heard on hits like "La-La (Means I Love You)," "Didn't I (Blow Your Mind This Time)," and "Ready or Not Here I Come (Can't Hide From Love)."
Growing up in Philadelphia, Hart sang in a variety of groups as a teenager before founding the Delfonics
They released their first single, "La-La (Means I Love You)" in 1968.
The Hart brothers co-founded the group (originally called The Orphonics) in Philadelphia in the mid-1960s
The song La-La would go on to be one of their best-known hits, topping out at No. 4 on the Billboard Hot 100 singles chart.
The Delfonics' only Grammy win came in 1971 for Best R&B Vocal Performance by a Duo or Group for their hit "Didn't I (Blow Your Mind This Time),"
