There had been rumblings in the rock world as to why former Guns N Roses rhythm guitarist Izzy Stradlin isn't part of the ongoing reunion tour.

Those rumblings centred around money and earlier today, Stradlin basically confirmed on Twitter he wasn't given his fair share of cash to take part and share the stage with Axl Rose, Slash and Duff McKagan as part of the original band (sans drummer Steven Adler) on the "Not In This Lifetime Tour".

Now Izzy's tweet isn't directed at anybody, but it comes hot on the heels of Axl Rose explaining why his former song-writing buddy isn't on tour. Below is Stradlin's tweet, just his fourth ever. It's pretty clear who the "they" refers to.

Yeah, in true Stradlin fashion he says "moving right along."

His words seem to be responding to Rose, who spoke to a Brazilian TV station ahead of the band’s fall run of South American gigs — though Rose proclaimed not to know much more about Stradlin’s thoughts than anyone else.

I don’t really know what to say about Izzy," said Rose. "It’s like you could have a conversation and think it’s one way, and the next day it’s another way. And I’m not trying to take any shots at Izzy. It’s just his thing is kind of his thing, whatever that is."

Sounds like Izzy's thing is getting paid equally compared with the rest of the band. He may not be as recognizable as Slash or Rose, even McKagan, but make no mistake, Stradlin was an integral cog and key songwriter on Guns' Appetite for Destruction and Use Your Illusions albums, as well as the Lies record.

It's a similar situation to that of Black Sabbath drummer Bill Ward, who wasn't offered a fair share of the revenue to partake in the legendary band's The End tour, so he declined to participate.
