Jack White has turned down the chance to appear on Slash’s debut solo album, according to the former Guns N’ Roses guitarist. Slash is due to release ‘Slash & Friends’ in early 2010, and the album reportedly features a host of guest musicians, including the likes of Flea, Dave Grohl, and Alice Cooper. However, the one artist that Slash says he really wanted to appear was Jack White – however, The White Stripes mainman was apparently reluctant to sing on the record. “I wanted to get Jack White to sing on something, but he didn’t want to sing,” Slash told Musicradar.com. “He said I’ll play drums, I’ll play guitar, but I don’t wanna sing. He was one guy that I wanted to work with. Pretty much everyone else that I went after I managed to get.” Writing on his Twitter.com/Slashhudson account, the guitarist said he hopes to have the album completely finished by the end of November.
