On Saturday night (May 11th) Steven Tyler and Marilyn Manson were the special guests of the Hollywood Vampires during their gig at L.A.'s Greek Theatre. The touring version of the Vampires features co-founders Joe Perry, Alice Cooper, and actor Johnny Depp -- along with supporting musicians Glen Sobel on drums, Chris Wyse on bass, and Buck Johnson on keyboard and vocals.

Blabbermouth.net reported that Steven Tyler joined the band for Tiny Bradshaw's "The Train Kept A-Rollin'" -- a longtime Aerosmith standard, with Marilyn Manson tackling Alice Cooper's "I'm Eighteen." Other highlights performed by the Vampires at the gig were covers of the Doors' "Break On Through," AC/DC's "The Jack," David Bowie's "'Heroes'," the Who's "Baba O'Riley" and Pink Floyd's "Another Brick In The Wall Pt. II" tagged on to the show closing rendition of Cooper's "School's Out."

Steven Tyler told us that although he's obviously not onstage all the time -- make no mistake, there's nothing about him that's an act: "I don’t obviously dress as I do on stage, because that’s like my 'superhero' look -- but I don’t hide because I’m not embarrassed. I’m very grateful for everything I’ve ever gotten, and unfortunately, the me that’s me is me when you see me. A little hard to go out in public, but I’m kinda, sorta, the same guy. If anything, people say, ‘Wow, you’re nicer that I thought,' 'cause they have this image of the scarves and microphone, and the clothes of that guy on stage that’s grimacing and growling and screaming, 'Dream On' -- but I’m not far from that guy, I like to stay true."
