This is a profound song...can't the "dona dona dona die" be the wordless response to the winds that only laugh at the impossibility of a calf growing wings. Or that justice can actually be achieved. Is there an implication that the calf may become an angel, a martyr perhaps? The suggestion that one can choose to be either a bird or a calf seems to exist in the last verse...and maybe feeds into the notion of the new jew in the promised land...or are the jews who made it out of the Nazi clutches the birds now free? Some sing this song not with resignation but with bitterness at the indifference of the winds... some find triumph that they learned to "fly"... such a mixed message song from 1940?..perhaps "blowing in the wind" redeems the wind after all?
