A voice of his own. The occasion was JFK’s inaugural, where Frost did not exactly forget his lines but seemed to have trouble reading what he had written (though if he needed to read them then he had indeed forgotten a poem he had just composed). He proceeded to recite, instead of his inaugural poem, “The Gift Outright.”
I’m inclined to think that Auden was right, though. Maybe Frost disliked the new poem and preferred the old one. Maybe he liked playing the visually compromised old poet. In any case, the moment provoked a wonderful poem by Richard Wilbur which I’ll post here if I can find it.
Auden was the man.
