The Beatles issued a double A-side single containing "Strawberry Fields Forever" and "Penny Lane" – their first new music since "Revolver" – in February 1967. The accompanying promotional films eschewed performance in favour of avant-garde imagery; they showed the band members' adoption of facial hair, a detail that challenged the convention for youthful-looking pop stars. The films confused many of their fans and drew unfavourable responses from the audience on "American Bandstand", the leading pop music show in the US. When the single failed to reach number one on the "Record Retailer" chart, British press agencies speculated that the group's run of success might have ended, with headlines such as "Beatles Fail to Reach the Top", "First Time in Four Years" and "Has the Bubble Burst?" However, the American cultural press, responding to appreciations of the Beatles' artistry in "Time" and "Newsweek", lauded the two songs for their experimental qualities. According to author Bernard Gendron, "An adult Beatlemania was in effect replacing the apparently fading 'teenybopper' Beatlemania, supplanting the screams and rituals of worship with breathless reportage and grandiloquent praise."
