During a brand new interview with Billboard.com, former SKID ROW singer Sebastian Bach — who has toured with Axl Rose a number of times — was asked if the GUNS N' ROSES frontman's reunion with Slash surprised him. He responded: "Yes. Yes, it did. But I always thought that if you can go through my interviews and bullshit, all of the animosity from Axl towards Slash or anybody else in GUNS N' ROSES, he would hang out and we would drink a lot of booze and talk about bullshit, this and that, but at the end of every single night going into the early morning or late afternoon [laughs], he would always say, 'But Baz, never say never.' He would always end the night with a 'but you never can tell, you know, maybe someday.' One part of me was surprised and the other part was not surprised."

Back in 2011, Bach told the QMI Agency about the GUNS 'N ROSES singer: "Axl is one of a kind. I was too young to ever see THE DOORS but when I see old footage of Jim Morrison on stage, Axl has that kind of danger thing going on when he steps up to the mic. He's pretty fascinating."

He also spoke about his first meeting with Axl Rose back in 1989 when SKID ROW was opening for AEROSMITH at the L.A. Forum. He said: "Axl came down to do the song 'Train Kept A Rollin'' with Steven Tyler and he didn't know the words, and he came to my dressing room and he goes, 'Do you know the words to this?' and I go, 'Yes, I do!' So I sat down there with him. That was a crazy night."

In anticipation of his upcoming book, "18 And Life On Skid Row", Bach will embark on a U.S. spring tour that will incorporate an intimate acoustic set followed by a full electric live show. The tour kicks off on April 27 in Jacksonville, Florida and wraps up in Salt Lake City on June 3.

Bach's upcoming memoir "18 And Life On Skid Row" is now set for a June 28 release through Dey Street Books (formerly It Books), an imprint of HarperCollins Publishers.
