Task: Question Answering
Input (English): passage: 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. Brian Jones was the original leader of the group. The band's primary songwriters, Jagger and Richards, assumed leadership after Andrew Loog Oldham became the group's manager. Their musical focus shifted from covering blues songs to writing original material, a decision with which Jones did not agree. Jones left the band less than a month before his death in 1969, having already been replaced by Mick Taylor, who remained until 1974.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 continues on guitar in tandem with Richards. Following Wyman's departure in 1993, Darryl Jones joined as their touring bassist. The Stones' touring keyboardists have included Nicky Hopkins (1967--1982), Ian McLagan (1978--1981), Billy Preston (through the mid-1970s) and Chuck Leavell (1982--present).
