Ronald Frederick "Ronnie" Lane (1 April 1946 – 4 June 1997) was an English musician, songwriter, and producer who is best known as the bass guitarist and founding member of two prominent English rock and roll bands: the Small Faces where he was nicknamed "Plonk" (1965–69), and, after losing the band's frontman, the Faces, with two new members added to the line-up (from the Jeff Beck Group), who dubbed him "Three-Piece" (1969–73).
Subsequently Lane collaborated with other musicians, leading his own bands and pursuing a solo career, while remaining close to his former bandmates. In the late 1970s he was diagnosed with multiple sclerosis and was supported by charity projects and financial contributions from friends, former bandmates and fans. After suffering from the disease for 21 years, he died at 51.
For his work in both Small Faces and Faces, Lane was inducted posthumously into the Rock and Roll Hall of Fame in 2012.
