Lindsey Buckingham recalls that overcoming the drama surrounding the band's inter-personal relationships during the making of Rumours was a huge part of the album's success: "The best thing probably was, in some odd way, the fact that we rose above all of that and were almost able to tap into the heroic aspects of ourselves in order to do what needed to be done. Because, we'd had already had one successful album, and once Rumours became as successful as it obviously was going to become, we just realized that we just had to push through no matter what and that was what people responded to."
