http://www.laweekly.com/music/heres-what-it-felt-like-seeing-guns-n-roses-at-the-troubadour-6784478 When Steven Adler's current band Adler cancelled an April 1 show the Whisky, GNR fans saw this as a sign that Steven was joining GNR. But that's not the case. A source close to the band told me that Adler is having back surgery, which is the real reason he pulled out of the Whisky show. I've also been told he's not ready to tour with GNR, not yet, and maybe not ever.
