  In a previous paper we have calculated the decay $\tau\to\pi\nu_\tau\gamma$.
We used a given relative sign between the internal bremsstrahlung and the
structure dependent radiation, which has been used by several other authors
before. However, we believe that there are good arguments why the opposite sign
is the physical one. We briefly discuss these arguments and then investigate
how the predictions for the decay $\tau\to\pi\nu_\tau\gamma$ are affected by
this sign.
