When Joe Carter joined Underworld as Mike Baldwin's manager in May 2002, there was an instant love-hate relationship between him and Karen McDonald but she stayed loyal to husband Steve. In March 2003, Joe and Karen went out to a nightclub where he hoped to entice her away from her husband but his ploy failed. He then tried to bring Karen's jealousy to the surface and, to this end, went out on a couple of dates with Lisa Ibbetson, an attractive, blonde hotel manageress.
