The Rolling Stones are an English rock band formed in London, England in 1962. The first stable line-up consisted of Brian Jones (guitar, harmonica), Mick Jagger (lead vocals), Keith Richards (guitar, backing vocals), Bill Wyman (bass), Charlie Watts (drums), and Ian Stewart (piano). Stewart was removed from the official line-up in 1963 but continued as a touring member until his death in 1985. Jones left the band less than a month prior to his death in 1969, having already been replaced by Mick Taylor, who remained until 1974. After Taylor left the band, Ronnie Wood took his place in 1975 and has been on guitar in tandem with Richards ever since. Following Wyman's departure in 1993, Darryl Jones joined as their touring bassist. Touring keyboardists for the band have been Nicky Hopkins (1967–1982), Ian McLagan (1978–1981), Billy Preston (through the mid-1970s) and Chuck Leavell (1982–present). The band was first led by Brian Jones, but after teaming as the band's songwriters, Jagger and Richards assumed leadership while Jones dealt with legal and personal troubles.
