MÖTLEY CRÜE bassist Nikki Sixx has apparently dismissed former SKID ROW singer Sebastian Bach's latest online missive as a ploy to get "attention to sell some books."After Bach revealed in a a three-word tweet to a fan that he was asked to join MÖTLEY CRÜE more than two decades ago, Sixx quickly retorted that Bach's version of events never happened. Sebastian then took to his Facebook page to describe in some detail the circumstances behind his being asked to join the CRÜE, which included taking part in a full day's rehearsal with the band and a slew of phone calls between various managers, agents and label executives. "I was driven to rehearsal by Tommy Lee, and I spent a full day singing the MÖTLEY CRÜE set with the band MÖTLEY CRÜE," Bach wrote. "I remember the songs that Nikki asked me to sing that day. I remember the whole road crew's ecstatic reaction to us jamming together all day. And I remember Nikki's very generous, kind offer, at the end of our rehearsal, for me to join the band MÖTLEY CRÜE. I remember his exact words that he said to me in front of his whole road crew, Tommy and Mick [Mars] as well. It's not every day that your hero asks you to join his band." Bach didn't reveal the full details of what went down that day, promising his Facebook followers that he "will tell the complete story of Nikki offering me to join MÖTLEY CRÜE in my upcoming book, which will be arriving on bookshelves soon." He added: "I am not simply 'making this up'… I am not a liar. I am working on my book right now and I look forward to you all reading it. I plan on my book having even more information in it than one of my tweets does." Earlier today, Nikki tweeted what appeared to be a short response to Bach's online rant: "Someone needs attention to try and sell some books." He then added: "I always liked the term 'washed up.'"
