Rose recorded the final vocal tracks in January 2007. On February 22, 2007, the band's road manager Del James issued a press release stating there was no official release date but that recording had ended and mixing had begun. In a 2007 interview, Sebastian Bach said Rose had planned to have the album released by Christmas 2007 and that the delays might have been caused by business problems. In January 2007, Bach recorded backing vocals for "Sorry" at Electric Lady Studios. He described the song as "almost like doom metal with Axl singing really clean over this grinding, slow beat that is fucking mean, I cannot get it out of my head." Harpist Patti Hood, who had worked with Pitman on the album "Free Mars", and conductor Suzy Katayama also recorded parts.
