Duff is interviewed by Juan Di Natale on Rock & Pop 95.9 in Buenos Aires. He talks about Loaded, Guns N Roses and Velvet Revolver.
On Velvet Revolver when asked about the band's split he says "I wouldn't say Velvet Revolver split up - but still the way it ended - you work so hard together on a common goal and you see one person sort of split away from that goal - and it ends up putting an end to the band the way everyone knows it."
