What rock group had the hit song "My Sharona"?

The Knack was an American rock band based in Los Angeles that rose to fame with their first single, "My Sharona", an international number-one hit in 1979.

Singer Doug Fieger was a native of Oak Park, Michigan, a northern suburb of Detroit, Michigan, and grew up in the Coolidge area. The brother of attorney Geoffrey Fieger (later known for representing Jack Kevorkian in a series of assisted suicide cases). Fieger had previously played in a rock band called Sky as well as the Sunset Bombers. Although Sky had received a modest amount of acclaim, including being produced by Rolling Stones producer Jimmy Miller, the band broke up without having any chart success. As a result, Fieger made the decision to move to Los Angeles and start another band.

Shortly after arriving in L.A., Fieger met Berton Averre (lead guitar, backing vocals and keyboards), and the two started a songwriting partnership. Fieger had also known Bruce Gary (drums) for years before forming the Knack in 1978 with Prescott Niles (bass). Niles was the last to join, a week before the band's first show in June 1978. In the meantime, Fieger had been doubling on bass on a series of demos that the group had shopped to several record labels, all of which were rejected. Some of these songs later made up the band's debut album Get the Knack, and included "Good Girls Don't".
