I obviously don't know that Tonto it is toothpuller but I  do wonder if the noise could be there as a shot or way of making fun of Izzy maybe.

The first time I heard about Toothpuller came from before the DATS had been discovered..

The following appeared in Metalsludge in 2006. There was no way of really backing the veracity of it until the DATS were discovered years later. If someone made up the Dizzy quotes then they would have had to guess that there was a song called Toothpuller (which is unlikely) Thanks to the DAT photos we can say that the song did exist, that it did have vocals & that at least Dizzy thought it was awful...

“Izzy used to be a great songwriter- his contributions to Guns N’ Roses first album are phenomenal. But, its almost like the guy has lost the fire… I mean I saw the guy a couple years back in the studio… and he was showing me a song he had just written called "Toothpuller" – it was literally about him visiting the dentist and getting a tooth pulled out. [Dizzy then sings some of the lyrics] I mean… this is a guy who wrote some badass songs and now he’s writing about getting his tooth pulled… I mean come on… can you imagine Axl singing that live?’(Dizzy https://metalsludge.tv/classic/?p=30945 )

“in April 1995, Duff calls again: “I’m trying to write new songs for the next GN’R record. Come lend me a hand.” It’d been five years since I’d left Guns, but I told myself, “Well shit, after all, why not?” Duff and I wrote ten songs in one week, and also made demos of them. And I thought, “It’s so easy.” When you work with someone like Duff, who loves music in the same way you do, everything becomes simple.” (French Izzy interview, 2001)

Some other comments on the time....

“He's been writing; he wrote some stuff with Duff. He wants to write songs, but he doesn't wanna deal with the whole thing. And it took me a while to finally get to the point where I couldn't handle it either, y'know? He wants to write material, but he's not really sure what he wants to do. He's so laid back. He doesn't want to deal with any pressure. Izzy does what he wants to do.” (Slash Metal Hammer November 1995)

“We recorded 10 songs in eight days. It got me excited about music again. I realized how easy the whole process could be. Those sessions were fun and painless. We just had a great time.”(Izzy Los Angeles Daily News, March 20, 1998)

“I'm using a Music Man Stingray. I started using it onstage. I've always liked these basses. Actually, when we were trying to do the Guns album I broke this bass out, and it just sounded amazing. It's bigger and fatter sounding. (Duff Hit  parader June 1999)

Did a bunch of research on that time a few years back, Definitely would have spoken to Zombux about it.

If you think some of the CD era songs may have started from those sessions then listen to Tonto and tell me what you hear at 1:49

I noticed you brought the Curly Shuffle DAT in Iron Mountain up over at badapples. The engineer was Critter (Chris) Snyder and the assistant engineer was Jer Blair (Jeremy Blair). Both worked together on Obsolete by Fear Factory the year before this In 98 (when Dave Dominguez was  at Rumbo working with Guns) I believe they turned up after he left the project. As far as the name goes I'm sure its just a place holder but there is a song with that name by Jump 'n the Saddle Band as tribute to The Three Stooges, it's such an oddly weird name that i kind of suspect it comes from that.

The mix from The Village comes from March 2000 & will be way more complete than this DAT in that video as that is a 24 track SLAVE. There would have been 24 tracks on the Master as well but Drums (multiple mics) Bass ect would have pushed it over 24 tracks so engineers would link a second 24-track machine to the first one. That DAT in the video is from the second machine and likely contains guitar solo's and overdubs along with whatever electronic synths/ keys ect were added at the time (if any). I believe they used Neve consoles at Rumbo & definitely did at the Village.

Threw this together a few months back on Dragon, just a theory on why it may be called that and why it's likely real.

Unrelated but I mention Canoga park in this video & I actually meant Central Park. I later looked into LastFM and found anyone can name a song whatever they want so i wouldn't put any stock in the Dragons Kiss title, but Dragon however is probably real.
