I’ve always believed that if you don’t stay moving, they will throw dirt on you.

Anka frames longevity as a form of self-preservation: in entertainment (and public life generally), momentum signals relevance. “Stay moving” implies continual work—touring, writing, reinventing, pursuing new projects—so that critics, competitors, or the public cannot declare you finished. “Throw dirt on you” evokes burial, suggesting that stagnation invites premature obituaries, career-wise or reputationally. The line also hints at a pragmatic, show-business worldview: perception can be as decisive as talent, and the antidote to being written off is visible activity. It’s a credo of persistence and reinvention, especially resonant for artists navigating changing tastes over decades.
