Great song. I think that Myles would work well on it, adding a bit of "tenderness" to some spots to make the vocals more dynamic.
I'd hope for Back and Forth Again. It is in my top 4 (Watch This, Slither, Come On Come In *No particular order). It has one of my top Slash solos including GNR. Heck, I think that they could take that recording and have Axl re-singing Dover's vocals, with Duff re-doing the bass, and it would be a huge hit.
