Doug Fieger, lead singer for The Knack, died in Los Angeles on Sunday at age 57. He's best remembered for singing "My Sharona," which rose to no. 1 on the charts in 1979 to become one of the great one-hit wonders of its time. The catchy ode to sleeping with extremely young women, which Fieger co-wrote, enjoyed an extremely long life in the pop world. Run DMC sampled it for their hit "It's Tricky" in the 1980s and the 1994 movie Reality Bites gave it another revival when it included the song on its soundtrack. The Detroit-born Fieger suffered from lung cancer in 2004 and later brain cancer, which, according to Variety, was diagnosed after he forgot the lyrics to "My Sharona" onstage in Las Vegas.
