Former GUNS N' ROSES and current VELVET REVOLVER guitarist Slash has confirmed rumors that he spent time in rehab prior to the recording sessions for VELVET REVOLVER's new CD, "Libertad". Slash made the admission during a three-minute video interview with Sweden's Aftonbladet/Klick!, which can be viewed at this location.Matthew Flamm of Crain's New York Business reported last month that Slash sold his autobiography to HarperCollins. The British born, California-raised axeman will work with writer Anthony Bozza, who helped MÖTLEY CRÜE drummer Tommy Lee pen his memoir, "Tommyland". The manuscript is due to be delivered in the fall. A HarperCollins spokeswoman confirmed Slash's deal, according to Crain's New York Business. Slash, born Saul Hudson, left GUNS N' ROSES in 1996 following a rift with frontman Axl Rose. He went on to form the band VELVET REVOLVER with fellow ex-GN'R members Duff McKagan (bass) and Matt Sorum (drums). Also in the works is "W.A.R.: The Unauthorized Biography of W. Axl Rose", by British rock writer Mick Wall. The book is due out in Britain in the fall and is currently making the rounds of New York publishers. "[GUNS N' ROSES] is a great story, and it's not finished yet,'' says Wall's U.S. agent, Barbara Zitwer, referring to the unfinished album, entitled "Chinese Democracy", that Rose has been working on for years. Slash is not the first member of VELVET REVOLVER to land a publishing deal for his memoir. A year ago, it was announced that the group's lead singer, Scott Weiland (ex-STONE TEMPLE PILOTS) had inked a deal with Scribner to release his autobiography, which will include stories about his rise to rock stardom, his battles with drugs, and his life now that he's sober.
