Author John Einarson has written that during this period of their career, the Byrds enjoyed tremendous popularity among teenage pop fans, with their music receiving widespread airplay on Top 40 radio and their faces adorning countless teen magazines. Much was made at the time of the Byrds' unconventional dress sense, with their casual attire strikingly at odds with the prevailing trend for uniformity among contemporary beat groups. With all five members sporting Beatlesque moptop haircuts, Crosby dressed in a striking green suede cape, and McGuinn wearing a pair of distinctive rectangular "granny glasses", the band exuded California cool, while also looking suitably non-conformist. In particular, McGuinn's distinctive rectangular spectacles would go on to become popular among members of the burgeoning hippie counterculture in the United States.
