Abstract
We demonstrate that the "hard-pion" process can be correctly calculated by "soft-pion" techniques. The difficulty in earlier treatments by these methods is shown to be due to the fact that dispersing with an inappropriate invariant fixed omits important pole contributions. We criticize the derivation of the Kawarabayashi-Suzuki relationship.
