Slash on Vocals

[Steve McKagan]

For gods sake, can't you here it's Duff? But Slash is in the background.

I read a while that a person who was at that show said it was Duff. Don't know where I read it anymore though..

Slash only sings on Dust N' Bones with Axl right after the solo and Buick Mckane.

And from memory on the Slash site snakepit.org FAQ section Slash was asked about Sentimental Movie and said it wasn't him on it but Duff and West.. but imo it sure sounds like him.
