An updated analysis of vector and axial-vector spectral functions is
presented. The resonant contributions to the spectral integrals are shown to be
expressible as multiples of 4 pi^2 f_pi^2, encoding the scale of spontaneous
chiral symmetry breaking in QCD. Up to order T^2 this behavior carries over to
the case of finite temperature.
