Fieger said he had been clean and sober for 25 years
The lead singer of The Knack, Doug Fieger, who co-wrote the hit My Sharona, has died at the age of 57.
Fieger, who died on Sunday at his home in Los Angeles, had been battling cancer, and had undergone surgery to remove brain tumours in 2006.
"Our hearts are broken, we will miss you Doug," his band members posted on The Knack's official website.
My Sharona topped the US singles chart in 1979, and led to the group being hailed as the "next Beatles".
The song, co-written with Berton Averre, was inspired by an ex-girlfriend of the same name.
It was re-released in 1994 after featuring in the Ben Stiller film Reality Bites, and was later revealed to be on former US president George W Bush's iPod.
It reached number six in the UK and enjoyed a revival after appearing in a cereal advert last year.
Fieger had spoken frankly about his drug and alcohol abuse during the band's heyday, but recently revealed he had been living a healthy lifestyle for more than 25 years.
Former member Bruce Gary died of cancer in 2006, while Berton Averre and Prescott Niles still perform as The Knack.
