Question: Who is the keyboard player for the rolling stones?

Disambiguated questions and answers:
context: Leavell's first encounters with The Rolling Stones were auditions on Long View Farm for the spot of piano player alongside Ian Stewart for the Rolling Stones 1981 United States tour. Even though Ian McLagan was chosen, Leavell guested at the Rolling Stones' Atlanta gig on October 26, 1981. For the 1982 European Tour Leavell landed the position of keyboardist alongside Ian Stewart. Leavell continued to record with the Stones on their next two albums, during a time when the band was not touring. After Stewart's death in 1985, Leavell occupied the role of the group's keyboardist by himself, with the exception of the addition of Matt Clifford on the "Steel Wheels" record and tour. He has continued to tour and record with The Rolling Stones ever since, as well as recording with Mick Jagger and Keith Richards on solo projects. The Stones' most recent studio recording was in 2012, "Doom and Gloom". He continued to go on tour with The Rolling Stones, as of 2006, as part of their record-grossing A Bigger Bang Tour. He served as the unofficial "musical director" for the band and devised each night's set list with Mick Jagger. "It's my job to keep Mick, Keith, Charlie and Ronnie all happy", Leavell stated on his web page.

context: From 1970, Preston played keyboards (including piano, organ, clavinet and various synthesizers) for the Rolling Stones, sometimes alongside pianists Nicky Hopkins and Ian Stewart, on their albums "Sticky Fingers", "Exile on Main St.", "Goats Head Soup", "It's Only Rock 'n Roll" and "Black and Blue". As the band's primary touring keyboardist from 1973 to 1977, he also performed as a support act with his own band (including Mick Taylor on guitar) on their 1973 European tour. A Munich performance from this tour was documented on Preston's album "Live European Tour 1973". In 1974, along with Bruce Fisher, one of his regular songwriting collaborators in the 1970s, he composed one of Joe Cocker's biggest hits, "You Are So Beautiful". On October 11, 1975, he was the first musical guest on "Saturday Night Live"s series premiere episode. Preston's 1973 song "Do You Love Me" was the basis for the Rolling Stones' track "Melody", released on "Black and Blue" in 1976. Although two of his songs were included in the band's 1975 and 1976 live sets, the Stones and Preston parted company in 1977, mainly due to a disagreement over money. He continued to play on solo records by Stones members like Mick Jagger's "Wandering Spirit", and made appearances on the band's "Tattoo You" and "Bridges to Babylon".
