The guitarist tells Mitch Lafon (via Blabbermouth): "I've never met anybody that has so much genuine musical integrity. He won't whore himself out, he won't do anything for business or money. It's just about the music.

"And he won't defend himself in the press, because he doesn't think it matters. It's just about the music - that's all he cares about. I've worked with a lot of people in this business, and I've never seen, or met, anybody that was motivated purely by that desire to make art.

"And you can say whatever you want about it, because he's not gonna defend himself, but he is that, and that's for sure. Otherwise, there would have been a reunion, because the offers for money have been outrageous. But he would never do a reunion unless it was for something besides money."

Rose has come under fire for repeatedly taking to the stage hours after the scheduled start time. Fortus at first thought it was for effect, but he says he realises now it is more about Rose getting himself in the right frame of mind.

He adds: "For the longest time, when I first started with the band even, I thought it was by design. I thought, 'He has this worked out.' Because it's two hours after we're supposed to start, three hours, and the stadiums are full of people just booing.
