Brain also said this about it years later...

Extrakd [Steve Freeman] and Mirv [Marc Haggard] and I, when I wasn’t doing Guns stuff, we’d just jam in my living room type of thing. You know, we had, like, a ProTools setup and we were jamming, and we were trying to come up with songs for Guns. We were writing all these crazy songs to try to turn in and these were coming from, like, you know, Extrakd is an old school dj type – he’s a bass player, but he loves old school break beats and, you know, cratedigger type of guy – and so this shit we were putting together was crazy. You know, we were just kind of going like, “Okay, what samples should we find for Axl?” Like, “Well, he’s kind of like Julius Caesar”, so we were sampling Julius Caesar, looking for albums, you know, and old school crazy shit. And I think we sampled, like, Ben Hur and chopped it up and cut it up, and that became a jam called “Seven” – I think we called it “Seven”. And I remember bringing that to the studio to have – I think Roy Thomas Baker was producing at that point and, you know, we’d be playing the stuff and he’d be in.

Whilst obviously this is a different song to Mustache it supports the notion that members bringing songs in could direct what a song or idea was about, not just Axl.

I doubt Axl would know about that French drummer but I can believe Brain would. However all of that is a moot point as its just an isolated claim from a Youtube commentor with no supporting info from anywhere else.

To play devils advocate It may be worth noting that if this claim was real it wouldn't hinge on Axl's knowledge of the French drummer or Zorro. It was Brain who has mentioned before that it was he and EXTRAKD who were findings samples (eg) Ben Hur..

It's not like it was Axl who named a song after chicken, or called Better Three Dollar Pyramid. Everything suggests that the writing of these songs was a group effort.

But obviously anyone can make wild claims in comment sections. There is one guy would claims Paul Tobias wrote everything and another who is a mental Fink fan and has probably hounded all of us at some point.

Can you link the video please?

I vaguely remember seeing the image's of the Sympathy For The devil stuff now you mention it I think. Old school black VHS-S cases so yeah I would assume ADATs

I haven't heard the original leak of COTR since it leaked earlier this year but I believe it was way shorter with the end cut off. Havent compared the mixes yet they may be different. Monsters is way higher quality than the original leak, far higher bit rate.
