This Lifetime...". The tour's name is a reference to a 2012 interview in which Rose, when asked about when a potential reunion would happen, responded "not in this lifetime." The reunion was billed as a "regrouping" by the band instead of a full reunion, since Slash and McKagan were filling empty spots in the existing band lineup.
