Paul Stanley from Kiss was a producer at one time. He kept trying to change Welcome To the Jungle according to Slash or Axl and they said Fuck you, your outta here. Pretty much Mike Clink was the only guy that would take the job from what I remember. The hard part was getting them to studio or something.
Yea axl didn't take kindly to paul's idea that WTTJ wasn't "catchy" enough. He said fuck off and later went on to say he was a queer i think hahaha. I think the hard part was getting them in the studio without a hangover lol.
