PHILADELPHIA -- The man best known for singing and co-writing the 1979 smash ''Ain't No Stoppin' Us Now" has died of cancer.
R&B vocalist and songwriter Gene McFadden was 56. Mr. McFadden's family says he died yesterday at his home in Philadelphia.
Mr. McFadden and John Whitehead formed the Epsilons in their youth and became a prominent songwriting and performing duo at soul music powerhouse Philadelphia International Records.
''Ain't No Stoppin' Us Now" hit number one on the R&B chart and number 13 on the pop charts.
The duo also wrote several hits performed by others, including ''Back Stabbers" for the O'Jays and ''Wake Up Everybody" for Harold Melvin and the Blue Notes.
Whitehead was fatally shot in May 2004.
