When thinking about trends my mind always wanders to one of my favorite scenes from the Beatles' first feature film, "A Hard Days Night" (1964).
Here's the set-up for this brief, absolute gem of a scene that's all about trends and the people who spot and market them:
Just hours before the Beatles are to perform live on British television, Ringo is nowhere to be found. John, Paul and George split up to look for him, and along the way each Beatle has his own brief encounter of a strange kind. George's fate is to become an accidental one-man focus group for a trend-master . . .
